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 the Linux kernel that stems from the failure to free allocated memory when memory allocation fails in the vcapduprule function, which could...

SUSE CVE-2022-50293

In the Linux kernel, the following vulnerability has been resolved: btrfs: do not BUGON on ENOMEM when dropping extent items for a range If we get -ENOMEM while dropping file extent items in a given range, at btrfsdropextents, due to failure to allocate memory when attempting to increment the...

SUSE CVE-2022-50308

In the Linux kernel, the following vulnerability has been resolved: ASoC: qcom: Add checks for devmkcalloc As the devmkcalloc may return NULL, the return value needs to be checked to avoid NULL poineter dereference...

Temporal OSS Server Vulnerable to Allocation of Resources Without Limits or Throttling

Insufficiently specific bounds checking on authorization header could lead to denial of service in the Temporal server on all platforms due to excessive memory allocation. This issue affects all platforms and versions of OSS Server prior to 1.26.3, 1.27.3, and 1.28.1 i.e., fixed in 1.26.3, 1.27.3...

DEBIAN-CVE-2023-53242

In the Linux kernel, the following vulnerability has been resolved: thermal/drivers/hisi: Drop second sensor hi3660 The commit 74c8e6bffbe1 "driver core: Add allocsize hint to devm allocators" exposes a panic "BRK handler: Fatal exception" on the hi3660thermalprobe funciton. This is because the...

CVE-2022-50293

CVE-2022-50293 affects the Linux kernel btrfs subsystem. When dropping file extent items for a range, ENOMEM could trigger a BUG_ON() path in btrfs_drop_extents(); the fix replaces those BUG_ON()s with proper transaction abort and error return handling. This means that instead of halting the tran...
