From: Jianglei Nie <niejianglei2021@163.com> stable inclusion from stable-v5.10.132 commit c1d9702ceb4a091da6bee380627596d1fba09274 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5YS3T Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 067d2521874135267e681c19d42761c601d503d6 ] On failure to allocate the SHA1 tfm, IMA fails to initialize and exits without freeing the ima_algo_array. Add the missing kfree() for ima_algo_array to avoid the potential memory leak.
