Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 4.14. It stems from the failure of the drm/fb-helper to delay initialization when fbdevprobe fails, resulting in an old modeset being submitted even when modeset-fb is empty, thereby triggering a WARNON!set-fb...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel versions prior to 6.6.160, 6.12.113, 6.18.57, and 7.2.11. This vulnerability arises because a lock is not held when calling dmtablegetmodenewmap via doresume; concurrent ioctl operations on the same device may swap tables after dmswaptable but befor...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 2.6.13. It stems from emtextchange failing to verify whether the algo array ends with NUL before passing it to textsearchprepare, potentially leading to out-of-bounds reads and kernel memory leaks...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 3.16. It arises because memstickcheck checks before setting eject/removing; subsequent requests are silently discarded without any action being taken, causing the removal process to hang and blocking the work queue...

Linux kernel security vulnerabilities

A security vulnerability exists in the Linux kernel; it arises when reading the write-only HRST and CLIRQ registers triggers a command, causing a dump of regular registers to result in a reset of the development board...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel versions from 5.10.270 up to and including 5.11, from 5.15.221 up to and including 5.16, from 6.1.188 up to and including 6.2, from 6.6.157 up to and including 6.6.160, from 6.12.109 up to and including 6.12.114, from 6.18.50 up to and including...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 5.16. It arises because amt devices’ buffers of skb objects reference the original pointers within their skb-cb fields. When these buffers are released due to a tunnel expiration, subsequent enqueuing operations trigger reuse after release i...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 4.20. It arises because bpfflowdissect fails to enforce hlen to U16MAX prior to clamping it when processing offsets returned by BPF programs. If hlen exceeds 65535, it is truncated to U16MAX, causing nhoff and thoff to be forced to zero. Thi...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: free the skb when the DLC has no owner rfcomm recv data hands the skb to d-data ready and returns 0 without freeing it, so the callback owns the skb from that point on. The tty implementation frees it when the...

Linux kernel security vulnerabilities

A security vulnerability exists in the Linux kernel. It stems from the fact that seg6makeflowlabel fails to use skbgethashnet to obtain a network pointer. When an skb lacks both skb-dev and skb-sk, skbflowdissect triggers a warning due to the absence of a network pointer; this may result in null...
