In the Linux kernel, the following vulnerability has been resolved: ice: fix potential NULL pointer deref in error path of icesetringparam icesetringparam nullifies tstampring of temporary txrings, without clearing ICETXRINGFLAGSTXTIME bit. When ICETXRINGFLAGSTXTIME is set and the subsequent...

CVE-2026-53007

CVE-2026-53007 affects the Linux kernel ice driver. The vulnerability arises when ice_set_ringparam() clears tstamp_ring of temporary tx_rings without clearing ICE_TX_RING_FLAGS_TXTIME. If ICE_TX_RING_FLAGS_TXTIME is set and ice_setup_tx_ring() then fails, unwinding can dereference a NULL tstamp_...

In the Linux kernel, the following vulnerability has been resolved: net/sched: schdualpi2: drain both C-queue and L-queue in dualpi2change Fix dualpi2change to correctly enforce updated limit and memlimit values after a configuration change of the dualpi2 qdisc. Before this patch, dualpi2change...

CVE-2026-52957 libceph: Fix potential null-ptr-deref in decode_choose_args()

In the Linux kernel, the following vulnerability has been resolved: libceph: Fix potential null-ptr-deref in decodechooseargs A message of type CEPHMSGOSDMAP contains an OSD map that itself contains a CRUSH map. When decoding this CRUSH map in crushdecode, an array of maxbuckets CRUSH buckets is...

CVE-2026-52938

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF storage. A race condition can occur where a storage element is accessed after its associated map has been deallocated, leading to a null pointer dereference. This can cause a kernel crash, resulting in a Denial of Service DoS for t...

CVE-2026-52939

A flaw was found in the Linux kernel's Reliable Datagram Sockets RDS component. An unprivileged local user can trigger a kernel panic by sending a specially crafted atomic control message cmsg over an active RDS/InfiniBand IB connection. This issue is caused by improper handling of masked atomic...

In the Linux kernel, the following vulnerability has been resolved: net/rds: fix NULL deref in rdsibsendcqehandler on masked atomic completion rdsibxmitatomic always programs a masked atomic opcode IBWRMASKEDATOMICCMPANDSWP or IBWRMASKEDATOMICFETCHANDADD for every RDS atomic cmsg. But the...

CVE-2026-52929

In the Linux kernel, the following vulnerability has been resolved: sctp: stream: fully roll back denied add-stream state When ADDOUTSTREAMS is denied, SCTP only shrinks the queued chunks and then lowers outcnt. That leaves removed stream metadata behind, so a later re-add can reuse a stale ext a...
