CVE-2026-89719

A flaw was found in the Linux kernel's zram module. This vulnerability occurs when the readblockstate function calculates the number of pages before acquiring a device lock. If the zram device is reset and reinitialized with a smaller disk size, the function can attempt to access memory beyond th...

kernel: zram: fix use-after-free in zram_bvec_write_partial()

A flaw was found in the Linux kernel, specifically within the zram module. This vulnerability is a use-after-free error, where the system attempts to use a piece of memory after it has been freed. This occurs when the zrambvecwritepartial function allows an asynchronous read to write into a page...

The vulnerability of the zram_bvec_write_partial() function in the drivers/block/zram/zram_drv.c module of the Linux kernel allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the zrambvecwritepartial function in the drivers/block/zram/zramdrv.c module of the Linux kernel is related to the use of memory after it is freed. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the...

CVE-2026-46089

A flaw was found in the Linux kernel's zram module. This vulnerability allows a local user to cause a system hang, leading to a Denial of Service DoS. The issue occurs because the zram module fails to properly handle partial discard requests, specifically by not calling endio when such requests a...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the fact that the zram module does not call bioendio when processing certain discard requests. Th...
