24 Dec 2025 — In the Linux kernel, the following vulnerability has been resolved: ima: Handle error code returned by ima_filter_rule_match() In ima_match_rules(), if ima_filter_rule_match() returns -ENOENT due to the rule being NULL, the function incorrectly skips the 'if (!rc)' check and sets 'result = true'. The LSM rule is considered a match, causing extra files to be measured by IMA. This issue can be reproduced in the following scenario: After unloading the SELinux policy module via 'semodule -d', if an IMA measurem... • https://git.kernel.org/stable/c/4af4662fa4a9dc62289c580337ae2506339c4729 •

24 Dec 2025 — In the Linux kernel, the following vulnerability has been resolved: isdn: mISDN: hfcsusb: fix memory leak in hfcsusb_probe() In hfcsusb_probe(), the memory allocated for ctrl_urb gets leaked when setup_instance() fails with an error code. Fix that by freeing the urb before freeing the hw structure. Also change the error paths to use the goto ladder style. Compile tested only.

If the first succeeds and a later one fails, the routine will leak memory. This patch fixes commit 2865d42c78a9 ("staging: r8712u: Add the new driver to the mainline kernel").
