21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: scsi: ibmvfc: Remove BUG_ON in the case of an empty event pool In practice the driver should never send more commands than are allocated to a queue's event pool. In the unlikely event that this happens, the code asserts a BUG_ON, and in the case that the kernel is not configured to crash on panic returns a junk event pointer from the empty event list causing things to spiral from there. This BUG_ON is a historical artifact of the ibmvfc dri... • https://git.kernel.org/stable/c/e1d1f79b1929dce470a5dc9281c574cd58e8c6c0 • CWE-476: NULL Pointer Dereference •

21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: fs/jfs: Add check for negative db_l2nbperpage l2nbperpage is log2(number of blks per page), and the minimum legal value should be 0, not negative. In the case of l2nbperpage being negative, an error will occur when subsequently used as shift exponent. Syzbot reported this bug: UBSAN: shift-out-of-bounds in fs/jfs/jfs_dmap.c:799:12 shift exponent -16777216 is negative En el kernel de Linux, se resolvió la siguiente vulnerabilidad: fs/jfs: ag... • https://git.kernel.org/stable/c/cc61fcf7d1c99f148fe8ddfb5c6ed0bb75861f01 • CWE-1335: Incorrect Bitwise Shift of Integer •
