The following security bugs were fixed:
- CVE-2021-22555: A heap out-of-bounds write affecting Linux was
discovered in net/netfilter/x_tables.c (bnc#1188116).
- CVE-2021-33909: fs/seq_file.c did not properly restrict seq buffer
allocations, leading to an integer overflow, an Out-of-bounds Write, and
escalation to root by an unprivileged user, aka CID-8cae8cd89f05
(bnc#1188062).
- CVE-2021-3609: A use-after-free in can/bcm could have led to privilege
escalation (bsc#1187215).
- CVE-2021-3612: An out-of-bounds memory write flaw was found in the
joystick devices subsystem in versions before 5.9-rc1, in the way the
user calls ioctl JSIOCSBTNMAP. This flaw allowed a local user to crash
the system or possibly escalate their privileges on the system. The
highest threat from this vulnerability is to confidentiality, integrity,
as well as system availability (bnc#1187585 ).
- CVE-2021-35039: kernel/module.c in the Linux kernel mishandled Signature
Verification, aka CID-0c18f29aae7c. Without CONFIG_MODULE_SIG,
verification that a kernel module is signed, for loading via
init_module, did not occur for a module.sig_enforce=1 command-line
argument (bnc#1188080).
The following non-security bugs were fixed:
- ACPI: APEI: fix synchronous external aborts in user-mode (git-fixes).
- ACPI: bus: Call kobject_put() in acpi_init() error path (git-fixes).
- ACPICA: Fix memory leak caused by _CID repair function (git-fixes).
- ACPI: EC: Make more Asus laptops use ECDT _GPE (git-fixes).
- ACPI: processor idle: Fix up C-state latency if not ordered (git-fixes).
- ACPI: property: Constify stubs for CONFIG_ACPI=n case (git-fixes).
- ACPI: resources: Add checks for ACPI IRQ override (git-fixes).
- ACPI: sysfs: Fix a buffer overrun problem with description_show()
(git-fixes).
- ALSA: hda/realtek: Add another ALC236 variant support (git-fixes).
- ALSA: hda/realtek: Fix bass speaker DAC mapping for Asus UM431D
(git-fixes).
- ALSA: intel8x0: Fix breakage at ac97 clock measurement (git-fixes).
- ALSA: isa: Fix error return code in snd_cmi8330_probe() (git-fixes).
- ALSA: usb-audio: fix rate on Ozone Z90 USB headset (git-fixes).
- ALSA: usb-audio: scarlett2: Fix wrong resume call (git-fixes).
