Linux 9P Network Protocol Heap Buffer Overflow DoS

The vulnerability of the p9pduvreadf function in the net/9p/protocol.c module of the 9P network protocol implementation in the Linux operating system is related to the use of an uninitialized variable during memory deallocation. Exploiting this vulnerability could allow a remote attacker to...

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: ethtool: Fix uninitialized number of lanes

In the Linux kernel, the following vulnerability has been resolved: ethtool: Fix uninitialized number of lanes It is not possible to set the number of lanes when setting link modes using the legacy IOCTL ethtool interface. Since 'struct ethtoollinkksettings' is not initialized in this path, drive...

UBUNTU-CVE-2021-47462

In the Linux kernel, the following vulnerability has been resolved: mm/mempolicy: do not allow illegal MPOLFNUMABALANCING | MPOLLOCAL in mbind syzbot reported access to unitialized memory in mbind 1 Issue came with commit bda420b98505 "numa balancing: migrate on fault among multiple bound nodes"...

CVE-2021-47462

CVE-2021-47462 affects the Linux kernel mempolicy/memory policy handling. The root cause was an invalid combination check for MPOL_MODE_FLAGS: MPOL_F_NUMA_BALANCING may only pair with MPOL_BIND, but the check existed only in do_set_mempolicy(). The patch moves this validation into sanitize_mpol_f...
