CVE-2022-41218 2 Debian, Linux 2 Debian Linux, Linux Kernel 2024-03-25 N/A 5.5 MEDIUM
In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused by refcount races, affecting dvb_demux_open and dvb_dmxdev_release.
CVE-2022-40768 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-03-25 N/A 5.5 MEDIUM
drivers/scsi/stex.c in the Linux kernel through 5.19.9 allows local users to obtain sensitive information from kernel memory because stex_queuecommand_lck lacks a memset for the PASSTHRU_CMD case.
CVE-2022-36946 3 Debian, Linux, Netapp 7 Debian Linux, Linux Kernel, Active Iq Unified Manager and 4 more 2024-03-25 N/A 7.5 HIGH
nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len.
CVE-2022-23222 4 Debian, Fedoraproject, Linux and 1 more 19 Debian Linux, Fedora, Linux Kernel and 16 more 2024-03-25 7.2 HIGH 7.8 HIGH
kernel/bpf/verifier.c in the Linux kernel through 5.15.14 allows local users to gain privileges because of the availability of pointer arithmetic via certain *_OR_NULL pointer types.
CVE-2021-44733 5 Debian, Fedoraproject, Linux and 2 more 20 Debian Linux, Fedora, Linux Kernel and 17 more 2024-03-25 4.4 MEDIUM 7.0 HIGH
A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11. This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object.
CVE-2021-43976 5 Debian, Fedoraproject, Linux and 2 more 23 Debian Linux, Fedora, Linux Kernel and 20 more 2024-03-25 2.1 LOW 4.6 MEDIUM
In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).
CVE-2021-42327 3 Fedoraproject, Linux, Netapp 18 Fedora, Linux Kernel, H300e and 15 more 2024-03-25 4.6 MEDIUM 6.7 MEDIUM
dp_link_settings_write in drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c in the Linux kernel through 5.14.14 allows a heap-based buffer overflow by an attacker who can write a string to the AMD GPU display drivers debug filesystem. There are no checks on size within parse_write_buffer_into_params when it uses the size of copy_from_user to copy a userspace buffer into a 40-byte heap buffer.
CVE-2021-37159 3 Debian, Linux, Oracle 5 Debian Linux, Linux Kernel, Communications Cloud Native Core Binding Support Function and 2 more 2024-03-25 4.4 MEDIUM 6.4 MEDIUM
hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.
CVE-2021-34693 2 Debian, Linux 2 Debian Linux, Linux Kernel 2024-03-25 2.1 LOW 5.5 MEDIUM
net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized.
CVE-2021-33200 3 Fedoraproject, Linux, Netapp 19 Fedora, Linux Kernel, Cloud Backup and 16 more 2024-03-25 7.2 HIGH 7.8 HIGH
kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.
CVE-2021-32606 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2024-03-25 7.2 HIGH 7.8 HIGH
In the Linux kernel 5.11 through 5.12.2, isotp_setsockopt in net/can/isotp.c allows privilege escalation to root by leveraging a use-after-free. (This does not affect earlier versions that lack CAN ISOTP SF_BROADCAST support.)
CVE-2021-29155 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-03-25 2.1 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel through 5.11.x. 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. Specifically, for sequences of pointer arithmetic operations, the pointer modification performed by the first operation is not correctly accounted for when restricting subsequent operations.
CVE-2021-29154 4 Debian, Fedoraproject, Linux and 1 more 20 Debian Linux, Fedora, Linux Kernel and 17 more 2024-03-25 7.2 HIGH 7.8 HIGH
BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements, allowing them to execute arbitrary code within the kernel context. This affects arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c.
CVE-2021-28039 3 Linux, Netapp, Xen 4 Linux Kernel, Cloud Backup, Solidfire Baseboard Management Controller Firmware and 1 more 2024-03-25 2.1 LOW 6.5 MEDIUM
An issue was discovered in the Linux kernel 5.9.x through 5.11.3, as used with Xen. In some less-common configurations, an x86 PV guest OS user can crash a Dom0 or driver domain via a large amount of I/O activity. The issue relates to misuse of guest physical addresses when a configuration has CONFIG_XEN_UNPOPULATED_ALLOC but not CONFIG_XEN_BALLOON_MEMORY_HOTPLUG.
CVE-2021-28038 3 Debian, Linux, Netapp 4 Debian Linux, Linux Kernel, Cloud Backup and 1 more 2024-03-25 4.9 MEDIUM 6.5 MEDIUM
An issue was discovered in the Linux kernel through 5.11.3, as used with Xen PV. A certain part of the netback driver lacks necessary treatment of errors such as failed memory allocations (as a result of changes to the handling of grant mapping errors). A host OS denial of service may occur during misbehavior of a networking frontend driver. NOTE: this issue exists because of an incomplete fix for CVE-2021-26931.
CVE-2021-26932 4 Debian, Fedoraproject, Linux and 1 more 9 Debian Linux, Fedora, Linux Kernel and 6 more 2024-03-25 1.9 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel 3.2 through 5.10.16, as used by Xen. Grant mapping operations often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success or failure of each one is reported to the backend driver, and the backend driver then loops over the results, performing follow-up actions based on the success or failure of each operation. Unfortunately, when running in PV mode, the Linux backend drivers mishandle this: Some errors are ignored, effectively implying their success from the success of related batch elements. In other cases, errors resulting from one batch element lead to further batch elements not being inspected, and hence successful ones to not be possible to properly unmap upon error recovery. Only systems with Linux backends running in PV mode are vulnerable. Linux backends run in HVM / PVH modes are not vulnerable. This affects arch/*/xen/p2m.c and drivers/xen/gntdev.c.
CVE-2021-26931 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-03-25 1.9 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel 2.6.39 through 5.10.16, as used in Xen. Block, net, and SCSI backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially being at least under the influence of guests (such as out of memory conditions), it isn't correct to assume a plain bug. Memory allocations potentially causing such crashes occur only when Linux is running in PV mode, though. This affects drivers/block/xen-blkback/blkback.c and drivers/xen/xen-scsiback.c.
CVE-2021-26930 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-03-25 4.6 MEDIUM 7.8 HIGH
An issue was discovered in the Linux kernel 3.11 through 5.10.16, as used by Xen. To service requests to the PV backend, the driver maps grant references provided by the frontend. In this process, errors may be encountered. In one case, an error encountered earlier might be discarded by later processing, resulting in the caller assuming successful mapping, and hence subsequent operations trying to access space that wasn't mapped. In another case, internal state would be insufficiently updated, preventing safe recovery from the error. This affects drivers/block/xen-blkback/blkback.c.
CVE-2021-42739 5 Debian, Fedoraproject, Linux and 2 more 8 Debian Linux, Fedora, Linux Kernel and 5 more 2024-03-24 4.6 MEDIUM 6.7 MEDIUM
The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandles bounds checking.
CVE-2021-29725 4 Ibm, Linux, Microsoft and 1 more 6 Aix, Secure External Authentication Server, Sterling Secure Proxy and 3 more 2024-03-19 5.0 MEDIUM 7.5 HIGH
IBM Secure External Authentication Server 2.4.3.2, 6.0.1, 6.0.2 and IBM Secure Proxy 3.4.3.2, 6.0.1, 6.0.2 could allow a remote user to consume resources causing a denial of service due to a resource leak.
