Linux: >> Linux Kernel >> 2.6.31.4 Security Vulnerabilities
In the Linux kernel before 5.2.14, rds6_inc_info_copy in net/rds/recv.c allows attackers to obtain sensitive information from kernel stack memory because tos and flags fields are not initialized.

An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system.

An issue was discovered in the Linux kernel before 5.0.4. The 9p filesystem did not protect i_size_write() properly, which causes an i_size_read() infinite loop and denial of service on SMP systems.

In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process because of a missing arch/powerpc/kernel/process.c check.

In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via an interrupt. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE is misused in arch/powerpc/kernel/process.c.

An issue was discovered in the Linux kernel before 4.16.7. A use-after-free can be caused by the function rsi_mac80211_detach in the file drivers/net/wireless/rsi/rsi_91x_mac80211.c.

An issue was discovered in the Linux kernel before 5.0.10. SMB2_read in fs/cifs/smb2pdu.c has a use-after-free. NOTE: this was not fixed correctly in 5.0.10; see the 5.0.11 ChangeLog, which documents a memory leak.
