In the Linux kernel, the following vulnerability has been resolved: tracing: Have trace_event_file have ref counters The following can crash the kernel: # cd /sys/kernel/tracing # echo 'p:sched schedule' > kprobe_events # exec 5>>events/kprobes/sched/enable # > kprobe_events # exec 5>&- The above commands: 1. Change directory to the tracefs directory 2. Create a kprobe event (doesn't matter what one) 3. Open bash file descriptor 5 on the enable file of the kprobe event 4. Delete the kprobe event (removes the files too) 5. • https://git.kernel.org/stable/c/e6807c873d8791ae5a5186ad05ec66cab926539a https://git.kernel.org/stable/c/407bf1c140f0757706c0b28604bcc90837d45ce2 https://git.kernel.org/stable/c/fa6d449e4d024d8c17f4288e0567d28ace69415c https://git.kernel.org/stable/c/a46bf337a20f9edd3c8041b025639842280d0575 https://git.kernel.org/stable/c/9beec04370132a7a6cd1aa9897f6fffc6262ff28 https://git.kernel.org/stable/c/f5ca233e2e66dc1c249bf07eefa37e34a6c9346a https://git.kernel.org/stable/c/961c4511c7578d6b8f39118be919016ec3db1c1e https://git.kernel.org/stable/c/a98172e36e5f1b3d29ad71fade2d611cf •

In the Linux kernel, the following vulnerability has been resolved: can: dev: can_put_echo_skb(): don't crash kernel if can_priv::echo_skb is accessed out of bounds If the "struct can_priv::echoo_skb" is accessed out of bounds, this would cause a kernel crash. Instead, issue a meaningful warning message and return with an error. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: can: dev: can_put_echo_skb(): no bloquee el kernel si se accede a can_priv::echo_skb fuera de los límites. Si se accede a "struct can_priv::echoo_skb" fuera de los límites, esto provocaría un fallo del kernel.
