SUSE 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...

CVE-2026-46011

A flaw was found in the Linux kernel's MediaTek JPEG mtk-jpeg driver. This use-after-free vulnerability arises from a race condition where the driver frees memory while it may still be in use by a work queue. This can allow a local attacker to cause system instability, leading to a denial of...

CVE-2026-38427

An issue in fetchjpg in xdrv10scripter.ino in Tasmota through 15.3.0.3 allows a remote attacker to cause heap buffer overflow. The Content-Length from a JPEG stream is stored in a uint16t variable; values above 65535 wrap around, causing allocation of a smaller buffer than the data actually read...
