- Summary
- proc: use the same treatment to check proc_lseek as ones for proc_read_iter et.al
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
proc: use the same treatment to check proclseek as ones for procread_iter et.al
Check pde->procops->proclseek directly may cause UAF in rmmod scenario. It's a gap in procregopen() after commit 654b33ada4ab("proc: fix UAF in procgetinode()"). Followed by AI Viro's suggestion, fix it in same manner.
