CVE-2026-31458

A flaw was found in the Linux kernel. A privileged local user can exploit this by manipulating the nrcontexts parameter in the mm/damon/sysfs interface to zero while the DAMON Data Access MONitor subsystem is active. This leads to a null pointer dereference when certain sysfs commands are...

CVE-2026-31445

A flaw was found in the Linux kernel. When updating DAMON Data Access MONitor parameters, an internal memory allocation failure during the damoncommitctx function could leave the DAMON context in a partially corrupted state. If this corrupted context is subsequently used, it can lead to unexpecte...

CVE-2026-31444

A flaw was found in ksmbd, a component of the Linux kernel. This vulnerability involves a use-after-free and a NULL pointer dereference within the smbgrantoplock function during the oplock publication sequence. An attacker could potentially exploit these issues, leading to memory corruption. This...

CVE-2026-31437

A flaw was found in the Linux kernel's netfs component. When a write operation is retried, the netfsunbufferedwrite function can attempt to access a non-existent function, leading to a NULL pointer dereference. This vulnerability can be triggered by specific filesystem configurations, such as 9P,...

CVE-2026-31436

A flaw was found in the Linux kernel's dmaengine subsystem, specifically within the idxd driver. This vulnerability occurs due to incorrect descriptor completion in the llistabortdesc function. This can lead to issues such as NULL pointer dereferences, double completion, or descriptor leaks, whic...

EUVD-2026-24841

In the Linux kernel, the following vulnerability has been resolved: tracing: Drain deferred trigger frees if kthread creation fails Boot-time trigger registration can fail before the trigger-data cleanup kthread exists. Deferring those frees until late init is fine, but the post-boot fallback mus...

EUVD-2026-24821

In the Linux kernel, the following vulnerability has been resolved: xfrm: iptfs: only publish modedata after clone setup iptfsclonestate stores x-modedata before allocating the reorder window. If that allocation fails, the code frees the cloned state and returns -ENOMEM, leaving x-modedata pointi...
