Description
CVE-2024-26935 addresses a regression in the Linux kernel's SCSI core related to the improper removal of procfs host directories. The issue arises from a duplicate or missing call to remove the proc directory under certain error conditions, leading to warnings and potential resource leaks. The fix involves conditionally removing the proc directory only when appropriate, preventing duplicate removal attempts and associated warnings.
