CVE-2022-50271

CVE-2022-50271 affects the Linux kernel’s vhost/vsock code. The issue arises when copying large files over SFTP over vsock, where data sizes commonly reach 32 kB and kmalloc may allocate many 32 kB chunks, leading to a page allocation failure (example: vhost-5837). The root cause is an inefficien...

CVE-2022-50271 vhost/vsock: Use kvmalloc/kvfree for larger packets.

In the Linux kernel, the following vulnerability has been resolved: vhost/vsock: Use kvmalloc/kvfree for larger packets. When copying a large file over sftp over vsock, data size is usually 32kB, and kmalloc seems to fail to try to allocate 32 32kB regions. vhost-5837: page allocation failure:...

CVE-2023-53242: Undefined Security Weakness

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-2023-53239: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: drm/msm/mdp5: Add check for kzalloc As kzalloc may fail and return NULL pointer, it should be better to check the return value in order to avoid the NULL pointer dereference. Patchwork:...
