kernel: libceph: fix potential use-after-free in have_mon_and_osd_map()

A use-after-free vulnerability was found in the Ceph client session initialization in the Linux kernel. The havemonandosdmap function checks map epochs without holding the appropriate locks, racing with concurrent map updates that free the old map. This can result in dereferencing freed memory...

Linux kernel block devices driver null_init_tag_set Heap Buffer Overflow

The vulnerability of the nullinittagset function in the drivers/block/nullblk/main.c module of the Linux kernel’s block devices driver is related to insufficient validation of input data. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...
