PT-2026-61370

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the bio integrity copy user function where the bip vcnt variable is incorrectly overwritten. Because bio integrity add page already sets bip vcnt to 1 for the bounce...

PT-2026-61369

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A null-pointer dereference exists in the bio integrity map user function. This occurs because pin user pages fast may only partially succeed in pinning pages, and the bio integrity map...

PT-2026-61389

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A bio leak occurs in the nvme module when an integrity mapping fails. This happens because the local bio is always NULL, causing the system to leak the bio instead of retrieving it...

CVE-2026-43278

The vulnerability CVE-2026-43278 affects the Linux kernel’s device-mapper (dm) component, notably dm-multipath, where stale cloned bio pointers in cloned requests can lead to use-after-free and double-free of bios. The sequence shows cloned bios freed during blk_complete_request() while rq->bi...

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 bio pointer in the cloning request in the dm driver is not cleared after the la...

JLSEC-2026-233 openssl-src vulnerable to Use-after-free following `BIO_new_NDEF`

The public API function BIOnewNDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by end user applications. The function receives a BIO from the...

Issue summary: Writing large, newline-free data into a BIO chain using the line-buffering filter where the next BIO performs short writes can trigger a heap-based out-of-bounds write. Impact summary: This out-of-bounds write can cause memory corruption which typically results in a crash, leading ...
