CVE-2026-23377

CVE-2026-23377 affects the Linux kernel in the ice network driver under XDP. The root cause is an incorrect use of frag_size in XDP RxQ info, which should reflect the whole buffer size but was treated as a DMA write length, causing negative tailroom and potential kernel panic when crafting packet...

CVE-2026-23345

In the Linux kernel, the following vulnerability has been resolved: arm64: gcs: Do not set PTESHARED on GCS mappings if FEATLPA2 is enabled When FEATLPA2 is enabled, bits 8-9 of the PTE replace the shareability attribute with bits 50-51 of the output address. The PAGEGCS,RO definitions include th...

CVE-2026-23345

The CVE-2026-23345 issue affects the Linux kernel on ARM64 with Graphics Control System (GCS) mappings when FEAT_LPA2 is enabled. The root cause is incorrect handling of PTE_SHARED bits in GCS memory mappings, which can trigger a kernel panic (DoS) due to a bad page table translation. The recomme...

FreeBSD -- Remote denial of service via null pointer dereference

Problem Description: On a system exposing an NVMe/TCP target, a remote client can trigger a kernel panic by sending a CONNECT command for an I/O queue with a bogus or stale CNTLID. Impact: An attacker with network access to the NVMe/TCP target can trigger an unauthenticated Denial of Service...

CVE-2026-23274

A flaw was found in the Linux kernel's netfilter: xtIDLETIMER module. This vulnerability occurs when revision 0 rules attempt to reuse a timer label previously created by revision 1 with alarm timer semantics. This action can lead to calling modtimer on an uninitialized timer list. A local attack...
