In the Linux kernel, the following vulnerability has been resolved:
drm/plane: Move range check for format_count earlier (CVE-2021-47659)
In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Fix some memory leaks in an error handling path of 'log_replay()' (CVE-2021-47660)
A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub-component. This flaw allows a local attacker with a user privilege to cause a denial of service. (CVE-2022-1184)
With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference. (CVE-2022-1789)
A NULL pointer dereference flaw was found in the Linux kernel's KVM module, which can lead to a denial of service in the x86_emulate_insn in arch/x86/kvm/emulate.c. This flaw occurs while executing an illegal instruction in guest in the Intel CPU. (CVE-2022-1852)
A use-after-free vulnerability was found in the Linux kernel's Netfilter subsystem in net/netfilter/nf_tables_api.c. This flaw allows a local attacker with user access to cause a privilege escalation issue. (CVE-2022-1966)
A use-after-free flaw was found in the Linux kernel in log_replay in fs/ntfs3/fslog.c in the NTFS journal. This flaw allows a local attacker to crash the system and leads to a kernel information leak problem. (CVE-2022-1973)
A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and possibly to run code. (CVE-2022-2078)
A flaw was found in hw. Incomplete cleanup of multi-core shared buffers for some Intel(r) Processors may allow an authenticated user to enable information disclosure via local access. (CVE-2022-21123)
A flaw was found in hw. Incomplete cleanup of microarchitectural fill buffers on some Intel(r) Processors may allow an authenticated user to enable information disclosure via local access. (CVE-2022-21125)
A flaw was found in hw. Incomplete cleanup in specific special register write operations for some Intel® Processors may allow an authenticated user to enable information disclosure via local access. (CVE-2022-21166)
net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free. (CVE-2022-32250)
An issue was discovered in the Linux kernel through 5.18.3 on powerpc 32-bit platforms. There is a buffer overflow in ptrace PEEKUSER and POKEUSER (aka PEEKUSR and POKEUSR) when accessing floating point registers. (CVE-2022-32981)
rpmsg_virtio_add_ctrl_dev in drivers/rpmsg/virtio_rpmsg_bus.c in the Linux kernel before 5.18.4 has a double free. (CVE-2022-34494)
rpmsg_probe in drivers/rpmsg/virtio_rpmsg_bus.c in the Linux kernel before 5.18.4 has a double free. (CVE-2022-34495)
