CVE-2022-49052

Summary (CVE-2022-49052) : The Linux kernel memory management path mm/page_io.c with zram swap could expose zeroed data to a process during CLONE_VM cloning, leading to potential data corruption. The root cause was the bogus swap_slot_free_notify in the CLONE_VM scenario, which didn’t correctly t...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from a page mapping exception during zram swapping, which could lead to user process corruption...

The vulnerability of the zram_meta_alloc() function in the zram module of Linux operating systems allows attackers to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the zrammetaalloc function in the zram module of Linux operating systems is related to the use of memory after it is freed. Exploiting this vulnerability can allow an attacker to compromise the confidentiality, integrity, and accessibility of protected information...
