CVE-2026-89942 iio: buffer: Fix potential use-after-free in anonymous buffer release

In the Linux kernel, the following vulnerability has been resolved: iio: buffer: Fix potential use-after-free in anonymous buffer release An anonymous buffer handle holds a reference to the underlying IIO device. The reference is dropped in the buffer handle's release function. If the device has...

CVE-2026-68179

A flaw was found in the Linux kernel's Network Shared Memory NSM module. A local attacker can exploit an issue in the nsmdevioctl function where an incorrect mutex unlock operation is performed. This occurs when an initial data copy fails, leading to an attempt to unlock a mutex that was never...

CVE-2026-68179

In the Linux kernel, the following vulnerability has been resolved: misc: nsm: only unlock nsmdev on post-lock error paths nsmdevioctl jumps to the common out label even when the initial copyfromuser fails before nsm-lock has been taken. The error path then blindly unlocks a mutex that was never...

CVE-2026-68179

CVE-2026-68179 affects the Linux kernel NSM: nsm_dev_ioctl() may unlock a mutex that was never acquired when pre-lock copy_from_user() fails, risking a local DoS. A patch changes control flow to return immediately on pre-lock failures and to keep the unlock path for post-lock errors only. The vul...

CVE-2026-68179 misc: nsm: only unlock nsm_dev on post-lock error paths

In the Linux kernel, the following vulnerability has been resolved: misc: nsm: only unlock nsmdev on post-lock error paths nsmdevioctl jumps to the common out label even when the initial copyfromuser fails before nsm-lock has been taken. The error path then blindly unlocks a mutex that was never...

CVE-2026-64343

A flaw was found in the Linux kernel. A race condition exists in the ldusb USB driver where a mutexunlock operation can attempt to access a mutex structure after it has been freed. This occurs when the release and disconnect functions race, leading to a use-after-free vulnerability. A local...
