UBUNTU-CVE-2026-46063

In the Linux kernel, the following vulnerability has been resolved: x86/shstk: Prevent deadlock during shstk sigreturn During sigreturn the shadow stack signal frame is popped. The kernel does this by reading the shadow stack using normal read accesses. When it can't assume the memory is shadow...

EUVD-2026-32304

In the Linux kernel, the following vulnerability has been resolved: hwmon: powerz Avoid cacheline sharing for DMA buffer Depending on the architecture the transfer buffer may share a cacheline with the following mutex. As the buffer may be used for DMA, that is problematic. Use the high-level DMA...

CVE-2026-46007 hwmon: (powerz) Avoid cacheline sharing for DMA buffer

In the Linux kernel, the following vulnerability has been resolved: hwmon: powerz Avoid cacheline sharing for DMA buffer Depending on the architecture the transfer buffer may share a cacheline with the following mutex. As the buffer may be used for DMA, that is problematic. Use the high-level DMA...

CVE-2026-46007

CVE-2026-46007 targets the Linux kernel hwmon: powerz code, where a DMA transfer buffer may accidentally share a cacheline with a mutex, enabling a cacheline sharing risk for DMA. The issue is mitigated by using the high‑level DMA helpers to ensure no cacheline sharing occurs, and by removing the...

kernel: net: skbuff: propagate shared-frag marker through frag-transfer helpers

A flaw was found in the Linux kernel's networking skbuff component. When skbtrycoalesce attaches paged fragments, it can lose the SKBFLSHAREDFRAG marker. This can lead to the Encapsulating Security Payload ESP input decrypting data in place over page-cache backed fragments, potentially resulting ...
