kernel: ext4: fix bug_on in __es_tree_search caused by bad boot loader inode

A flaw was identified in the ext4 filesystem implementation in the Linux kernel where a malformed or improperly initialized boot loader inode could trigger a BUGON condition inside the estreesearch function. This occurs when the inode’s mode imode is an unexpected type and the code does not...

CVE-2021-47406

In the Linux kernel, the following vulnerability has been resolved: ext4: add error checking to ext4extreplaysetiblocks If the call to ext4mapblocks fails due to an corrupted file system, ext4extreplaysetiblocks can get stuck in an infinite loop. This could be reproduced by running generic/526 wi...

USN-6777-3 linux-gcp vulnerabilities

Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service system crash. CVE-2023-47233 Several...
