https://notcve.org/view.php?id=CVE-2023-1195
A use-after-free flaw was found in reconn_set_ipaddr_from_hostname in fs/cifs/connect.c in the Linux kernel. The issue occurs when it forgets to set the free pointer server->hostname to NULL, leading to an invalid pointer request. • https://github.com/torvalds/linux/commit/153695d36ead0ccc4d0256953c751cabf673e621 https://access.redhat.com/security/cve/CVE-2023-1195 https://bugzilla.redhat.com/show_bug.cgi?id=2154171 • CWE-416: Use After Free •
