| CVE-2025-4878 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-06-30 | 3.6 Low |
| A vulnerability was found in libssh, where an uninitialized variable exists under certain conditions in the privatekey_from_file() function. This flaw can be triggered if the file specified by the filename doesn't exist and may lead to possible signing failures or heap corruption. | ||||
| CVE-2026-11791 | 1 Redhat | 3 389 Directory Server, Directory Server, Enterprise Linux | 2026-06-30 | 5 Medium |
| A flaw was found in 389 Directory Server. During schema reload, the attr_syntax_swap_ht() function unconditionally frees attribute syntax information nodes, bypassing the refcount-based deferred deletion used elsewhere in the attribute syntax subsystem. If an administrator triggers schema reload while concurrent LDAP query traffic is active, worker threads may access freed memory, resulting in use-after-free or double-free and a denial of service (server crash). | ||||

| CVE-2026-13595 | 3 Kernel, Linux, Redhat | 7 Util-linux, Util-linux, Enterprise Linux and 4 more | 2026-06-30 | 6.8 Medium |
| A flaw was found in the libblkid library of util-linux. During nested partition probing, the BSD, Minix, Solaris x86, and UnixWare partition probers cache a raw pointer to a parent partition entry in a dynamically allocated array. When subsequent partition additions cause the array to be reallocated, this pointer becomes stale, leading to a heap use-after-free read. An attacker who can present a crafted block device image (for example, via USB insertion or a loop-mounted disk image) can trigger this flaw without user interaction, as libblkid is invoked automatically by udev/udisks as root on block-device hot-plug events. This could lead to limited information disclosure or denial of service. | ||||
| CVE-2025-32988 | 2 Gnu, Redhat | 10 Gnutls, Ceph Storage, Discovery and 7 more | 2026-06-30 | 6.5 Medium |
| A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not own, leading to a double-free condition when the parent function or caller later attempts to free the same structure. This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of service or memory corruption, depending on allocator behavior. | ||||
| CVE-2025-48798 | 1 Redhat | 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more | 2026-06-30 | 7.3 High |
| A flaw was found in GIMP when processing XCF image files. If a user opens one of these image files that has been specially crafted by an attacker, GIMP can be tricked into making serious memory errors, potentially leading to crashes and causing use-after-free issues. | ||||
| CVE-2025-12105 | 1 Redhat | 2 Enterprise Linux, Enterprise Linux Eus | 2026-06-29 | 7.5 High |
| A flaw was found in the asynchronous message queue handling of the libsoup library, widely used by GNOME and WebKit-based applications to manage HTTP/2 communications. When network operations are aborted at specific timing intervals, an internal message queue item may be freed twice due to missing state synchronization. This leads to a use-after-free memory access, potentially crashing the affected application. Attackers could exploit this behavior remotely by triggering specific HTTP/2 read and cancel sequences, resulting in a denial-of-service condition. | ||||
| CVE-2025-0622 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-06-29 | 6.4 Medium |
| A flaw was found in command/gpg. In some scenarios, hooks created by loaded modules are not removed when the related module is unloaded. This flaw allows an attacker to force grub2 to call the hooks once the module that registered it was unloaded, leading to a use-after-free vulnerability. If correctly exploited, this vulnerability may result in arbitrary code execution, eventually allowing the attacker to bypass secure boot protections. | ||||
| CVE-2023-32253 | 1 Redhat | 1 Enterprise Linux | 2026-06-29 | 5.9 Medium |
| A flaw was found in the Linux kernel's ksmbd component. A deadlock is triggered by sending multiple concurrent session setup requests, possibly leading to a denial of service. | ||||
| CVE-2025-26601 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-06-29 | 7.8 High |
| A use-after-free flaw was found in X.Org and Xwayland. When changing an alarm, the values of the change mask are evaluated one after the other, changing the trigger values as requested, and eventually, SyncInitTrigger() is called. If one of the changes triggers an error, the function will return early, not adding the new sync object, possibly causing a use-after-free when the alarm eventually triggers. | ||||
| CVE-2025-26600 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-06-29 | 7.8 High |
| A use-after-free flaw was found in X.Org and Xwayland. When a device is removed while still frozen, the events queued for that device remain while the device is freed. Replaying the events will cause a use-after-free. | ||||
| CVE-2025-26594 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-06-29 | 7.8 High |
| A use-after-free flaw was found in X.Org and Xwayland. The root cursor is referenced in the X server as a global variable. If a client frees the root cursor, the internal reference points to freed memory and causes a use-after-free. | ||||
| CVE-2026-53296 | 1 Linux | 1 Linux Kernel | 2026-06-29 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: mailbox: mailbox-test: free channels on probe error On probe error, free the previously obtained channels. This not only prevents a leak, but also UAF scenarios because the client structure will be removed nonetheless because it was allocated with devm. | ||||
| CVE-2026-53300 | 1 Linux | 1 Linux Kernel | 2026-06-29 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: net: enetc: fix NTMP DMA use-after-free issue The AI-generated review reported a potential DMA use-after-free issue [1]. If netc_xmit_ntmp_cmd() times out and returns an error, the pending command is not explicitly aborted, while ntmp_free_data_mem() unconditionally frees the DMA buffer. If the buffer has already been reallocated elsewhere, this may lead to silent memory corruption. Because the hardware eventually processes the pending command and perform a DMA write of the response to the physical address of the freed buffer. To resolve this issue, this patch does the following modifications: 1. Convert cbdr->ring_lock from a spinlock to a mutex The lock was originally a spinlock in case NTMP operations might be invoked from atomic context. After downstream support for all NTMP tables, no such usage has materialized. A mutex lock is now required because the driver now needs to reclaim used BDs and release associated DMA memory within the lock's context, while dma_free_coherent() might sleep. 2. Introduce software command BD (struct netc_swcbd) The hardware write-back overwrites the addr and len fields of the BD, so the driver cannot rely on the hardware BD to free the associated DMA memory. The driver now maintains a software shadow BD storing the DMA buffer pointer, DMA address, and size. And netc_xmit_ntmp_cmd() only reclaims older BDs when the number of used BDs reaches NETC_CBDR_CLEAN_WORK (16). The software BD enables correct DMA memory release. With this, struct ntmp_dma_buf and ntmp_free_data_mem() are no longer needed and are removed. 3. Require callers to hold ring_lock across netc_xmit_ntmp_cmd() netc_xmit_ntmp_cmd() releases the ring_lock before the caller finishes consuming the response. At this point, if a concurrent thread submits a new command, it may trigger ntmp_clean_cbdr() and free the DMA buffer while it is still in use. Move ring_lock ownership to the caller to ensure the response buffer cannot be reclaimed prematurely. So the helpers ntmp_select_and_lock_cbdr() and ntmp_unlock_cbdr() are added. These changes eliminate the DMA use-after-free condition and ensure safe and consistent BD reclamation and DMA buffer lifecycle management. | ||||
| CVE-2026-53290 | 1 Linux | 1 Linux Kernel | 2026-06-29 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/xe/eustall: Fix drm_dev_put called before stream disable in close In xe_eu_stall_stream_close(), drm_dev_put() is called before the stream is disabled and its resources are freed. If this drops the last reference, the device structures could be freed while the subsequent cleanup code still accesses them, leading to a use-after-free. Fix this by moving drm_dev_put() after all device accesses are complete. This matches the ordering in xe_oa_release(). (cherry picked from commit 35aff528f7297e949e5e19c9cd7fd748cf1cf21c) | ||||
| CVE-2026-53294 | 1 Linux | 1 Linux Kernel | 2026-06-29 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: mailbox: mailbox-test: don't free the reused channel The RX channel can be aliased to the TX channel if it has a different MMIO. This special case needs to be handled when freeing the channels otherwise a double-free occurs. | ||||
| CVE-2026-53322 | 1 Linux | 1 Linux Kernel | 2026-06-29 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Clean up DMABUFs before disabling function On device shutdown, make vfio_pci_core_close_device() call vfio_pci_dma_buf_cleanup() before the function is disabled via vfio_pci_core_disable(). This ensures that all access via DMABUFs is revoked before the function's BARs become inaccessible. This fixes an issue where, if the function is disabled first, a tiny window exists in which the function's MSE is cleared and yet BARs could still be accessed via the DMABUF. The resources would also be freed and up for grabs by a different driver. | ||||
