  script_tag(name:"insight", value:"A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel.This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information.(CVE-2022-1353)

usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel through 5.17.1 has a double free.(CVE-2022-28388)

ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.(CVE-2022-28390)

Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access.(CVE-2022-0002)

Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access.(CVE-2022-0001)

Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB.An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to influence mispredicted branches.Then, cache allocation can allow the attacker to obtain sensitive information.(CVE-2022-23960)

A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free.This issue needs to handle return with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker.(CVE-2022-1016)

A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in the Linux kernel.This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality.(CVE-2022-0494)

In aio_poll_complete_work of aio.c, there is a possible memory corruption due to a use after free.This could lead to local escalation of privilege with no additional execution privileges needed.User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-185125206References: Upstream kernel(CVE-2021-39698)

In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota tree (on disk).This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a corrupted quota file.(CVE-2021-45868)

A use-after-free flaw was found in the Linux kernel's network scheduling subsystem due to a race condition.This flaw allows a local user to cause a denial of service (memory corruption or crash) or privilege escalation.(CVE-2021-39713)

A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c.This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat.(CVE-2022-27666)
