The vulnerability in the function `serial8250_unregister_port()` of the `drivers/tty/serial/8250/8250_core.c` file, a driver for console TTY support on the serial port of the Linux kernel, allows a attacker to cause a service failure.

The vulnerability of the serial8250unregisterport function in the driver/tty/serial/8250/8250core.c file of the console support driver for the serial port in the Linux kernel is related to the failure to release resources after their useful period has ended. Exploiting this vulnerability could...

CVE-2026-31448

A flaw was found in the Linux kernel's ext4 filesystem. When creating a directory or node, if an extent insertion fails, the system may not properly clear residual data. This can lead to a situation where both directory and extended attribute xattr blocks simultaneously use the same memory buffer...

CVE-2026-35361

The mknod utility in uutils coreutils fails to handle security labels atomically by creating device nodes before setting the SELinux context. If labeling fails, the utility attempts cleanup using std::fs::removedir, which cannot remove device nodes or FIFOs. This leaves mislabeled nodes behind wi...

CVE-2026-35350

The CVE-2026-35350 entry concerns the cp utility in uutils coreutils. When using -p (preserve), if chown fails, the tool applies the source’s mode bits, potentially producing a user-owned copy with privileged bits (setuid/setgid) and violating local security policies. This behavior differs from G...
