CVE-2026-46077

In the Linux kernel, the following vulnerability has been resolved: crypto: atmel-tdes - fix DMA sync direction Before DMA output is consumed by the CPU, -dmaaddrout must be synced with dmasyncsingleforcpu instead of dmasyncsinglefordevice. Using the wrong direction can return stale cache data on...

CVE-2026-46069

In the Linux kernel, the following vulnerability has been resolved: wifi: mwifiex: fix use-after-free in mwifiexadaptercleanup The mwifiexadaptercleanup function uses timerdelete non-synchronous for the wakeuptimer before the adapter structure is freed. This is incorrect because timerdelete does...

CVE-2026-46027

In the Linux kernel, the following vulnerability has been resolved: net/smc: avoid early lgr access in smcclcwaitmsg A CLC decline can be received while the handshake is still in an early stage, before the connection has been associated with a link group. The decline handling in smcclcwaitmsg...

CVE-2026-46011

In the Linux kernel, the following vulnerability has been resolved: media: mtk-jpeg: fix use-after-free in release path due to uncancelled work The mtkjpegrelease function frees the context structure ctx without first cancelling any pending or running work in ctx-jpegwork. This creates a race...
