CVE-2026-74406

A flaw was found in the Linux kernel's Virtual Extensible LAN VXLAN component. A race condition can occur where the udptunnelsockrelease function sets a socket's user data to NULL while the vxlangropreparereceive function is still actively using it. This could lead to a null pointer dereference,...

CVE-2026-74276

A flaw was found in the Linux kernel's spi: xilinx driver. The driver incorrectly determines the size of its internal buffer, a First-In, First-Out FIFO queue. This miscalculation can lead to an overflow when the driver attempts to write more data than the FIFO can hold during a Serial Peripheral...

CVE-2026-74301

A flaw was found in the Linux kernel's Bluetooth driver. An error in handling Bluetooth packets can cause a memory leak, where a data structure is not properly released. This continuous leakage of memory could potentially lead to system instability or a denial of service...

CVE-2026-74362

A flaw was found in the Linux kernel's ext2 filesystem. When performing write operations on files opened with OSYNC or ODSYNC flags, the system call write2 could incorrectly report success to a local user even if the data synchronization to disk failed. This could lead to data integrity issues, a...

CVE-2026-74380

A flaw was found in the Linux kernel's host1x GPU driver. An incorrect return value check in the iommumapsgtable function, coupled with an improper integer assignment in pinjob, could lead to negative value overflows. This vulnerability may result in data integrity issues or system instability...

CVE-2026-74373

A flaw was found in the Linux kernel's md/raid1 and raid10 components. This flaw involves incorrect accounting of block I/O bio operations for split cloned bios. When a failed bio is split and resubmitted, the system may either double count or miss accounting for these bios. This can lead to...

CVE-2026-74372

A flaw was found in the Linux kernel's RAID1 subsystem. When a REQATOMIC write operation encounters a bad block, a reference to the RAID device rdev is not properly released. This resource leak prevents the affected RAID device from being removed, potentially leading to a denial of service DoS...

CVE-2026-74354

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. A local attacker could exploit a locking issue within the zappages function. This vulnerability arises because zapvmarange requires a specific memory map lock mmaplock that, when acquired under certain conditions, can le...

CVE-2026-74369

A flaw was found in the Linux kernel's liveupdate component. This use-after-free vulnerability occurs due to an incorrect order of operations when managing file handler modules. Specifically, the system attempts to access module operations after the module's reference count has been decremented,...

CVE-2026-74293

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture System on Chip ASoC subsystem, specifically within the fslaudmix component. The fslaudmixputmixclksrc and fslaudmixputoutsrc functions do not properly validate user-provided enum values before processing them. This improper...

CVE-2026-74437

A flaw was found in the Linux kernel's uvcvideo module, which manages USB Video Class UVC devices. When a UVC camera with asynchronous control is in use, a specific sequence of operations can lead to a deadlock within the kernel. This vulnerability could allow a local attacker to cause a...

CVE-2026-74309

A flaw was found in the Linux kernel's vdpa/octeonep component. This vulnerability involves an incorrect mapping of Interrupt Request IRQ numbers to processing rings within the interrupt handler. The system incorrectly calculates the IRQ index, which can lead to misdirected or mishandled...

CVE-2026-74427

A flaw was found in the AFS Andrew File System component of the Linux kernel. During the teardown of an AFS network namespace, a work item responsible for managing preallocated resources rxrpc call/connection/peer queue may not be properly canceled. This improper resource handling could lead to a...

CVE-2026-74420

A flaw was found in the Linux kernel's GPU Shared Virtual Memory SVM subsystem. This vulnerability occurs when attempting to create an SVM range on Virtual Memory Areas VMAs that are not backed by physical page objects. An attacker could exploit this by triggering repeated page retrieval failures...

CVE-2026-74405

A flaw was found in the Linux kernel. A race condition exists within the Optimized Power Performance OPP subsystem, where a newly added OPP object is exposed before its internal reference count is fully initialized. A concurrent operation can then increment this uninitialized reference count,...

CVE-2026-74319

A flaw was found in the btrfs zoned filesystem within the Linux kernel. When performing data relocation, the system can enter a deadlock state. This happens because the relocation process waits for a space reservation ticket that cannot be fulfilled, as the relocation itself is the operation...

K000162987: Linux kernel vulnerability CVE-2026-53313

Security Advisory Description In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Avoid NULL dereference in dcdmubsrv error paths In dcdmubsrvlogdiagnosticdata and dcdmubsrvenabledpiatrace. Both functions check: if !dcdmubsrv || !dcdmubsrv-dmub and then call...

CVE-2026-58088

The ELF core dump code counted the number of dumpable VM map entries, allocated a buffer for the corresponding program headers, then iterated over the map a second time to populate them. A process sharing the address space via rfork2 can mutate the map between the two passes, causing the second...

CVE-2026-49424

The Linux waitid implementation translates a FreeBSD siginfot struct into a stack-declared Linux siginfot. It did not first zero the stack struct. An unprivileged user may observe 104 bytes of uninitialized kernel stack data, which may contain sensitive information...

CVE-2026-58084

To retrieve the previous timer value, the kernel calls realtimergettime, which obtains the current time for the timer's clock. For a timer using CLOCKTAI this can fail when no TAI offset has been configured, but the error return was not checked, so the uninitialized output buffer was copied to...
