In the Linux kernel, the following vulnerabilities have been resolved: ASoC: mediatek: common: Fixed a reference count leak in parsedailinkinfo. Added calls to ofnodeput before the returns from ofnodeget and ofnodeput, which can prevent imbalance if the “foreachavailablechildofnode” loop terminat...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Fixed a double-free in the dma-buf feature. The error path through vfiopcicorefeaturedmabuf ignores its own advice to only use dmabufput after dmabufexport. Instead, it proceeds through the entire unwind chain. In the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: smb: Client: Fixed issue where reference counting of @ses was missed. Use the new cifssmbsesincrefcount helper function to obtain an active reference to @ses and @ses-dfsrootses if set. This will prevent @ses-dfsrootses from...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: erofs: Fixed incorrect early exits for invalid “metabox-enabled” images. Crafted EROFS images with metadata compression enabled can trigger incorrect early returns, leading to folio reference leaks. However, this does not cause...
