kernel: powerpc/kprobes: Fix null pointer reference in arch_prepare_kprobe()

A flaw was found in the Linux kernel in archpreparekprobe: where certain error conditions are not properly validated before dereferencing a pointer. Under specific circumstances, this can result in a NULL pointer dereference in kernel space. If triggered, the kernel may generate an oops or panic,...

kernel: ext4: fix uninititialized value in 'ext4_evict_inode'

An uninitialized variable flaw was found in the Linux kernel's ext4 filesystem in the inode eviction path. A local user can trigger this issue by creating filesystem operations that cause inode allocation to fail before the iflags field is initialized, followed by inode cleanup that attempts to...

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-2023-52879

The CVE-2023-52879 issue concerns the Linux kernel tracing subsystem, specifically the trace_event_file object used for tracefs events. A use-after-free can occur when a kprobe event is deleted while a user-space process still holds an opened “enable” file descriptor for that event, because the u...
