CVE-2022-47520

An issue was discovered in the Linux kernel before 6.0.11. Missing offset validation in drivers/net/wireless/microchip/wilc1000/hif.c in the WILC1000 wireless driver can trigger an out-of-bounds read when parsing a Robust Security Network (RSN) information element from a Netlink packet.

An issue was discovered in the Linux kernel before 6.0.11. Missing offset validation in drivers/net/wireless/microchip/wilc1000/hif.c in the WILC1000 wireless driver can trigger an out-of-bounds read when parsing a Robust Security Network (RSN) information element from a Netlink packet.

Security Fix(es):

A use-after-free flaw was found in Linux kernel before 5.19.2. This issue occurs in cmd_hdl_filter in drivers/staging/rtl8712/rtl8712_cmd.c, allowing an attacker to launch a local denial of service attack and gain escalation of privileges.(CVE-2022-4095)

There are null-ptr-deref vulnerabilities in drivers/net/slip of linux that allow attacker to crash linux kernel by simulating slip network card from user-space of linux.

[Root cause]

When a slip driver is detaching, the slip_close() will act to cleanup necessary resources and sl->tty is set to NULL in slip_close(). Meanwhile, the packet we transmit is blocked, sl_tx_timeout() will be called. Although slip_close() and sl_tx_timeout() use sl->lock to synchronize, we don`t judge whether sl->tty equals to NULL in sl_tx_timeout() and the null pointer dereference bug will happen.

(Thread 1) | (Thread 2) | slip_close() | spin_lock_bh(&sl->lock) | ... ... | sl->tty = NULL //(1) sl_tx_timeout() | spin_unlock_bh(&sl->lock) spin_lock(&sl->lock); | ... | ... tty_chars_in_buffer(sl->tty)| if (tty->ops->..) //(2) | ... | synchronize_rcu()

We set NULL to sl->tty in position (1) and dereference sl->tty in position (2).

------------------------------------------(CVE-2022-41858)

A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw to potentially crash the system causing a denial of service.(CVE-2022-4129)

In (TBD) of (TBD), there is a possible way to corrupt kernel memory 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-220738351References: Upstream kernel(CVE-2022-20568)

In l2cap_chan_put of l2cap_core, there is a possible use after free due to improper locking. 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-165329981References: Upstream kernel(CVE-2022-20566)

Guests can trigger NIC interface reset/abort/crash via netback It is possible for a guest to trigger a NIC interface reset/abort/crash in a Linux based network backend by sending certain kinds of packets. It appears to be an (unwritten?) assumption in the rest of the Linux network stack that packet protocol headers are all contained within the linear section of the SKB and some NICs behave badly if this is not the case. This has been reported to occur with Cisco (enic) and Broadcom NetXtrem II BCM5780 (bnx2x) though it may be an issue with other NICs/drivers as well. In case the frontend is sending requests with split headers, netback will forward those violating above mentioned assumption to the networking core, resulting in said misbehavior.(CVE-2022-3643)

In verity_target of dm-verity-target.c, there is a possible way to modify read-only files due to a missing permission check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-234475629References: Upstream kernel(CVE-2022-20572)

A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their privileges on the system.(CVE-2022-4378)

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-2022-41218)

Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux kernel contained an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-36280)

Hyunwoo Kim discovered that the DVB Core driver in the Linux kernel did not properly perform reference counting in some situations, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-41218)

It was discovered that the Intel i915 graphics driver in the Linux kernel did not perform a GPU TLB flush in some situations. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-4139)

It was discovered that a race condition existed in the Xen network backend driver in the Linux kernel when handling dropped packets in certain circumstances. An attacker could use this to cause a denial of service (kernel deadlock). (CVE-2022-42328, CVE-2022-42329)

It was discovered that the Atmel WILC1000 driver in the Linux kernel did not properly validate offsets, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service (system crash). (CVE-2022-47520)

It was discovered that the network queuing discipline implementation in the Linux kernel contained a null pointer dereference in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-47929)

José Oliveira and Rodrigo Branco discovered that the prctl syscall implementation in the Linux kernel did not properly protect against indirect branch prediction attacks in some situations. A local attacker could possibly use this to expose sensitive information. (CVE-2023-0045)

It was discovered that a use-after-free vulnerability existed in the Advanced Linux Sound Architecture (ALSA) subsystem. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-0266)

Kyle Zeng discovered that the IPv6 implementation in the Linux kernel contained a NULL pointer dereference…
