kernel: Information leak when handling NM entries containing NUL

A vulnerability was found in the Linux kernel. Payloads of NM entries are not supposed to contain NUL. When such entry is processed, only the part prior to the first NUL goes into the concatenation i.e. the directory entry name being encoded by a bunch of NM entries. The process stops when the...

kernel: Infoleak/use-after-free in __oom_reap_task_mm function in mm/oom_kill.c

The oomreaptaskmm function in mm/oomkill.c in the Linux kernel, before 4.14.4, mishandles gather operations. This allows attackers to cause a denial of service TLB entry leak or use-after-free or possibly have unspecified other impact by triggering a copytouser call within a certain time window...

The vulnerability of the __oom_reap_task_mm function in the Linux operating system allows a hacker to trigger a service failure or exert other effects.

The vulnerability of the oomreaptaskmm function mm/oomkill.c in the Linux operating system is related to the use of memory after it is freed. Exploiting this vulnerability can allow a remote attacker to cause a service failure or other effects by using the copytouser function...
