CVE-2026-89488

A flaw was found in the Linux kernel's Open vSwitch OVS component. An unprivileged user, operating from a user and network namespace, can trigger a use-after-free vulnerability during network namespace teardown. This occurs because packet processing attempts to use connection tracking CT limit...

CVE-2026-89471

A flaw was found in the Linux kernel's crosusbpd-charger driver. A malicious or compromised embedded controller EC can report an excessive number of USB Power Delivery PD ports. This causes the driver to write beyond the allocated memory buffer when populating a fixed-size array for port data,...

CVE-2026-80986

A flaw was found in the Linux kernel's SMC-Rv2 network component. A remote attacker could exploit this vulnerability by sending a specially crafted message during an SMC-Rv2 link addition. This can lead to a slab-out-of-bounds write, potentially causing a system crash and resulting in a denial of...

CVE-2026-89723

A flaw was found in the nilfs2 file system component of the Linux kernel. When a file is truncated, an intermediate node block is not properly deleted and remains in the B-tree node cache. This can lead to the log writer incorrectly processing the block, resulting in a slab-out-of-bounds memory...

CVE-2026-81002

A flaw was found in the Linux kernel's XDP eXpress Data Path component. Incorrect handling of zero-copy frame layout in the xdpconvertzctoxdpframe function can allow an AFXDP zero-copy packet, when redirected through cpumap, to cause a memory corruption. This can lead to a slab-out-of-bounds erro...

CVE-2026-89754

In the Linux kernel, the following vulnerability has been resolved: mm/pagewalk: fix stale walk-action escaping walkpmdrange If -pmdentry sets walk-action = ACTIONAGAIN, the pmdnone check is retried. The PMD entry may be cleared at the point of retry. In this case, if walk-ops-installpte is not...

AZL-100169 CVE-2026-89746 affecting package kernel 6.6.150.1-1

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix use-after-free with same-name named triggers When two hist triggers on different events are registered with the same name=, the second one reuses the first as nameddata. Both are added to tr-histvars by savehistvars...

CVE-2026-89691

In the Linux kernel, the following vulnerability has been resolved: nfsd: clear opcnt on compound arg release to prevent OOB read nfsd4releasecompoundargs resets args-ops to the inline iops8 array when the dynamically-allocated ops buffer is freed, but leaves args-opcnt at its original value whic...

CVE-2026-89689

In the Linux kernel, the following vulnerability has been resolved: nfsd: don't free session slots that are still in use nfsd4sequence can free the very slot it is currently processing. When the session shrinker has reduced setargetmaxslots below sefchannel.maxreqs, the shrink path checks three...

DEBIAN-CVE-2026-89668

In the Linux kernel, the following vulnerability has been resolved: nfsd: move nfsddebugfsinit after nfsd4initslabs in initnfsd nfsddebugfsinit runs before nfsd4initslabs in initnfsd. If the slab allocation fails, the bare "return retval" bypasses nfsddebugfsexit, leaving orphan debugfs files wit...
