CVE-2022-1012

A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of service problem.

The Linux Kernel, the operating system core itself.

Security Fix(es):

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)

In the Linux kernel before 5.17.3, fs/io_uring.c has a use-after-free due to a race condition in io_uring timeouts. This can be triggered by a local user who has no access to any user namespace; however, the race condition perhaps can only be exploited infrequently.(CVE-2022-29582)

A use-after-free vulnerability was found in the Linux kernel in drivers/net/hamradio. This flaw allows a local attacker with a user privilege to cause a denial of service (DOS) when the mkiss or sixpack device is detached and reclaim resources early.(CVE-2022-1195)

In mmc_blk_read_single of block.c, there is a possible way to read kernel heap memory due to uninitialized data. This could lead to local information disclosure if reading from an SD card that triggers errors, with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-216481035References: Upstream kernel(CVE-2022-20008)

Due to the small table perturb size, a memory leak flaw was found in the Linux kernel’s TCP source port generation algorithm in the net/ipv4/tcp.c function. This flaw allows an attacker to leak information and may cause a denial of service.(CVE-2022-1012)

A flaw was found in the Linux kernel’s nfcmrvl_nci_unregister_dev() function. A race condition leads to a use-after-free issue when simulating the NFC device from the user space.(CVE-2022-1734)

Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions.(CVE-2022-29581)

A NULL pointer dereference flaw was found in the Linux kernel’s X.25 set of standardized network protocols functionality in the way a user terminates their session using a simulated Ethernet card and continued usage of this connection. This flaw allows a local user to crash the system.(CVE-2022-1516)

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

• kernel: Small table perturb size in the TCP source port generation algorithm can lead to information leak (CVE-2022-1012)

• kernel: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root (CVE-2022-32250)

This kernel update is based on upstream 5.15.41 and fixes at least the following security issues:

A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading to a possible out-of-bounds memory write in the Linux kernel BPF subsystem due to the way a user loads BTF. This flaw allows a local user to crash or escalate their privileges on the system. NOTE: Mageia kernels by default prevents unprivileged users from being able to use eBPF so this would require a privileged user with CAP_SYS_ADMIN or root to be able to abuse this flaw reducing its attack space (CVE-2022-0500).

Due to the small table perturb size, a memory leak flaw was found in the Linux kernel’s TCP source port generation algorithm in the net/ipv4/tcp.c function. This flaw allows an attacker to leak information and may cause a denial of service (CVE-2022-1012).

A flaw was found in the Linux kernel’s nfcmrvl_nci_unregister_dev() function. A race condition leads to a use-after-free issue when simulating the NFC device from the user space (CVE-2022-1734).

A flaw was found in the Linux kernel's adjust_ptr_min_max_vals in the kernel/bpf/verifier.c function. In this flaw, a missing sanity check for *_OR_NULL pointer types that perform pointer arithmetic may cause a kernel information leak issue. NOTE: Mageia kernels by default prevents unprivileged users from being able to use eBPF so this would require a privileged user with CAP_SYS_ADMIN or root to be able to abuse this flaw reducing its attack space (CVE-2022-23222).

The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state (CVE-2022-28893).

Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root (CVE-2022-29581).

Other fixes in this update:

• nfsd: Fix a write performance regression
• x86/mm: Include spinlock_t definition in pgtable.h

For other upstream fixes, see the referenced changelogs.

Due to the small table perturb size, a memory leak flaw was found in the Linux kernel’s TCP source port generation algorithm in the net/ipv4/tcp.c function. This flaw allows an attacker to leak information and may cause a denial of service (CVE-2022-1012).

A flaw was found in the Linux kernel’s nfcmrvl_nci_unregister_dev() function. A race condition leads to a use-after-free issue when simulating the NFC device from the user space (CVE-2022-1734).

A flaw was found in the Linux kernel's adjust_ptr_min_max_vals in the kernel/bpf/verifier.c function. In this flaw, a missing sanity check for *_OR_NULL pointer types that perform pointer arithmetic may cause a kernel information leak issue. NOTE: Mageia kernels by default prevents unprivileged users from being able to use eBPF so this would require a privileged user with CAP_SYS_ADMIN or root to be able to abuse this flaw reducing its attack space (CVE-2022-23222).

The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state (CVE-2022-28893).

Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root (CVE-2022-29581).
