  script_tag(name:"insight", value:"This kernel update is based on upstream 5.15.10 and fixes at least the
following security issues:

A read-after-free memory flaw was found in the Linux kernel's garbage
collection for Unix domain socket file handlers in the way users call
close() and fget() simultaneously and can potentially trigger a race
condition. This flaw allows a local user to crash the system or escalate
their privileges on the system (CVE-2021-4083).

An attacker can access kernel memory bypassing valid buffer boundaries by
exploiting implementation of control request handlers in the following usb
gadgets - rndis, hid, uac1, uac1_legacy and uac2. Processing of malicious
control transfer requests with unexpectedly large wLength lacks assurance
that this value does not exceed the buffer size. Due to this fact one is
capable of reading and/or writing (depending on particular case) up to 65k
of kernel memory. Devices implementing affected usb device gadget classes
may be affected by buffer overflow vulnerabilities resulting in information
disclosure, denial of service or execution of arbitrary code in kernel
context (CVE-2021-39685).

In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in drivers/net/
ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can
introduce a crafted device) to trigger an out-of-bounds write via a crafted
length value (CVE-2021-43975).

In addition to the upstream changes, we also have added the following fixes:
- [Bug 29704] Kernel 5.15.4 + Nouveau = flickering Plasma DE
- [Bug 29711] Firefox under plasma doesn't display gui with kernel 5.15.4
 and other gui issues.
- [Bug 29760] Kernel 5.15.x breaks bluetooth on Lifebook A555
- Add AHCI support for ASM1062+JBM575 cards
- fget: clarify and improve __fget_files() implementation
- drm/i915/gen11: Moving WAs to icl_gt_workarounds_init()
- HID: holtek: fix mouse probing
- iwlwifi: add new killer devices to the driver
- iwlwifi: add new device id 7F70
- iwlwifi: pcie: fix killer name matching for AX200
- iwlwifi: pcie: remove two duplicate PNJ device entries
- iwlwifi: add missing entries for Gf4 with So and SoF
- iwlwifi: swap 1650i and 1650s killer struct names
- iwlwifi: add new Qu-Hr device
- iwlwifi: add new ax1650 killer device
- rtw88: 8821c: support RFE type4 wifi NIC
- rtw88: 8821c: correct 2.4G tx power for type 2/4 NIC
- rtw88: 8821c: disable the ASPM of RTL8821CE as it causes systems to hang

For other upstream fixes, see the referenced changelogs.");
