2021-03-20 CVE-2021-28952 An issue was discovered in the Linux kernel through 5.11.8. The sound/soc/qcom/sdm845.c soundwire device driver has a buffer overflow when an unexpected port ID number is encountered, aka CID-1c668e1c0a0f. (This has been fixed in 5.12-rc4.) Fedora, Linux_kernel, A250_firmware, Aff_500f_firmware, Cloud_backup, Fas_500f_firmware, Solidfire_baseboard_management_controller_firmware 7.8
2021-03-20 CVE-2020-27170 An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-f232326f6966. This affects pointer types that do not define a ptr_limit. Ubuntu_linux, Debian_linux, Fedora, Linux_kernel 4.7
2021-03-20 CVE-2020-27171 An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c has an off-by-one error (with a resultant integer underflow) affecting out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-10d2bb2e6b1d. Ubuntu_linux, Debian_linux, Fedora, Linux_kernel 6.0
2021-03-22 CVE-2021-28964 A race condition was discovered in get_old_root in fs/btrfs/ctree.c in the Linux kernel through 5.11.8. It allows attackers to cause a denial of service (BUG) because of a lack of locking on an extent buffer before a cloning operation, aka CID-dbcc7d57bffc. Debian_linux, Fedora, Linux_kernel, Aff_a250_firmware, Cloud_backup, Fas_500f_firmware, Solidfire_baseboard_management_controller_firmware 4.7
2021-03-22 CVE-2021-28971 In intel_pmu_drain_pebs_nhm in arch/x86/events/intel/ds.c in the Linux kernel through 5.11.8 on some Haswell CPUs, userspace applications (such as perf-fuzzer) can cause a system crash because the PEBS status in a PEBS record is mishandled, aka CID-d88d05a9e0b6. Debian_linux, Fedora, Linux_kernel, Aff_500f_firmware, Aff_a250_firmware, Cloud_backup, Solidfire_baseboard_management_controller_firmware 5.5
2021-03-22 CVE-2021-28972 In drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux kernel through 5.11.8, the RPA PCI Hotplug driver has a user-tolerable buffer overflow when writing a new device name to the driver from userspace, allowing userspace to write data to the kernel stack frame directly. This occurs because add_slot_store and remove_slot_store mishandle drc_name '\0' termination, aka CID-cc7a0bb058b8. Fedora, Linux_kernel, Cloud_backup, Fas\/aff_baseboard_management_controller, Solidfire_baseboard_management_controller_firmware 6.7
2021-03-30 CVE-2021-29647 An issue was discovered in the Linux kernel before 5.11.11. qrtr_recvmsg in net/qrtr/qrtr.c allows attackers to obtain sensitive information from kernel memory because of a partially uninitialized data structure, aka CID-50535249f624. Debian_linux, Fedora, Linux_kernel 5.5
2021-03-30 CVE-2021-29646 An issue was discovered in the Linux kernel before 5.11.11. tipc_nl_retrieve_key in net/tipc/node.c does not properly validate certain data sizes, aka CID-0217ed2848e8. Fedora, Linux_kernel 5.5
2021-03-30 CVE-2021-29648 An issue was discovered in the Linux kernel before 5.11.11. The BPF subsystem does not properly consider that resolved_ids and resolved_sizes are intentionally uninitialized in the vmlinux BPF Type Format (BTF), which can cause a system crash upon an unexpected access attempt (in map_create in kernel/bpf/syscall.c or check_btf_info in kernel/bpf/verifier.c), aka CID-350a5c4dd245. Fedora, Linux_kernel 5.5
2021-03-30 CVE-2021-29649 An issue was discovered in the Linux kernel before 5.11.11. The user mode driver (UMD) has a copy_process() memory leak, related to a lack of cleanup steps in kernel/usermode_driver.c and kernel/bpf/preload/bpf_preload_kern.c, aka CID-f60a85cad677. Fedora, Linux_kernel 5.5
