SUSE CVE-2026-23252

In the Linux kernel, the following vulnerability has been resolved: xfs: get rid of the xchkxfiledescr calls The xchkxfiledescr macros call kasprintf, which can fail to allocate memory if the formatted string is larger than 16 bytes or whatever the nofail guarantees are nowadays. Some of them cou...

The vulnerabilities of the functions cifs_close_deferred_file() and cifs_close_all_deferred_files() in the fs/cifs/misc.c file of the Linux kernel’s file system allow a attacker to cause a service failure.

The vulnerabilities of the functions cifsclosedeferredfile and cifsclosealldeferredfiles in the fs/cifs/misc.c module of the Linux file system are related to improper memory release memory leaks. Exploiting these vulnerabilities can allow an attacker to cause a service failure...
