12 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: ssb: Fix potential NULL pointer dereference in ssb_device_uevent() The ssb_device_uevent() function first attempts to convert the 'dev' pointer to 'struct ssb_device *'. However, it mistakenly dereferences 'dev' before performing the NULL check, potentially leading to a NULL pointer dereference if 'dev' is NULL. To fix this issue, move the NULL check before dereferencing the 'dev' pointer, ensuring that the pointer is valid before attemptin... • https://git.kernel.org/stable/c/c5dc2d8eb3981bae261ea7d1060a80868e886813 •
