CVE-2023-40283
Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.
CVE-2022-4269
William Zhao discovered that a flaw in the Traffic Control (TC)
subsystem when using a specific networking configuration
(redirecting egress packets to ingress using TC action "mirred"),
may allow a local unprivileged user to cause a denial of service
(triggering a CPU soft lockup).
CVE-2022-39189
Jann Horn discovered that TLB flush operations are misshandled in
the KVM subsystem in certain KVM_VCPU_PREEMPTED situations, which
may allow an unprivileged guest user to compromise the guest kernel.
CVE-2023-1206
It was discovered that the networking stack permits attackers to
force hash collisions in the IPv6 connection lookup table, which may
result in denial of service (significant increase in the cost of
lookups, increased CPU utilization).
CVE-2023-1380
Jisoo Jang reported a heap out-of-bounds read in the brcmfmac
Wi-Fi driver. On systems using this driver, a local user could
exploit this to read sensitive information or to cause a
denial of service.
CVE-2023-2002
Ruiahn Li reported an incorrect permissions check in the Bluetooth
subsystem. A local user could exploit this to reconfigure local
Bluetooth interfaces, resulting in information leaks, spoofing,
or denial of service (loss of connection).
CVE-2023-2007
Lucas Leong and Reno Robert discovered a time-of-check-to-time-of-use
flaw in the dpt_i2o SCSI controller driver. A local user with access
to a SCSI device using this driver could exploit this for privilege escalation.
This flaw has been mitigated by removing support for the I2OUSRCMD operation.
CVE-2023-2124
Kyle Zeng, Akshay Ajayan and Fish Wang discovered that missing
metadata validation may result in denial of service or potential
privilege escalation if a corrupted XFS disk image is mounted.
CVE-2023-2269
Zheng Zhang reported that improper handling of locking in the
device mapper implementation may result in denial of service.
CVE-2023-2898
It was discovered that missing sanitising in the f2fs file system
may result in denial of service if a malformed file system is
accessed.
CVE-2023-3090
It was discovered that missing initialization in ipvlan networking may
lead to an out-of-bounds write vulnerability, resulting in denial of
service or potentially the execution of arbitrary code.
CVE-2023-3111
The TOTE Robot tool found a flaw in the Btrfs filesystem driver that can
lead to a use-after-free. It's unclear whether an unprivileged user can
exploit this.
CVE-2023-3212
Yang Lan that missing validation in the GFS2 filesystem could result in
denial of service via a NULL pointer dereference when mounting a
malformed GFS2 filesystem.
CVE-2023-3268
It was discovered that an out-of-bounds memory access in relayfs could
result in denial of service or an information leak.
CVE-2023-3338
Ornaghi Davide discovered a flaw in the DECnet protocol implementation
which could lead to a null pointer dereference or use-after-free. A
local user can exploit this to cause a denial of service (crash or
memory corruption) and probably for privilege escalation.
This flaw has been mitigated by removing the DECnet protocol implementation.
CVE-2023-3389
Querijn Voet discovered a use-after-free in the io_uring subsystem,
which may result in denial of service or privilege escalation.
CVE-2023-3611
It was discovered that an out-of-bounds write in the traffic control
subsystem for the Quick Fair Queueing scheduler (QFQ) which may
result in denial of service or privilege escalation.
CVE-2023-3609 / CVE-2023-3776 / CVE-2023-4128
It was discovered that a use-after-free in the cls_fw, cls_u32, cls_route and
network classifiers may result in denial of service or potential
local privilege escalation.
CVE-2023-3863
It was discovered that a use-after-free in the NFC implementation
may result in denial of service, an information leak or potential
local privilege escalation.
CVE-2023-4004
It was discovered that a use-after-free in Netfilter's implementation
of PIPAPO (PIle PAcket POlicies)may result in denial of service or
potential local privilege escalation for a user with the CAP_NET_ADMIN
capability in any user or network namespace.
CVE-2023-4132
A use-after-free in the driver for Siano SMS1xxx based MDTV receivers
may result in local denial of service.
CVE-2023-4147
Kevin Rich discovered a use-after-free in Netfilter when adding
a rule with NFTA_RULE_CHAIN_ID, which may result in local privilege
escalation for a user with the CAP_NET_ADMIN capability in any user
or network namespace.
CVE-2023-4194
A type confusion in the implementation of TUN/TAP network devices may
allow a local user to bypass network filters.
CVE-2023-4273
Maxim Suhanov discovered a stack overflow in the exFAT driver, which may
result in local denial of service via a malformed file system.
CVE-2023-20588
Jana Hofmann, Emanuele Vannacci, Cedric Fournet, Boris Koepf and Oleksii Oleksenko
discovered that on some AMD CPUs with the Zen1 micro architecture an integer
division by zero may leave stale quotient data from a previous division, resulting
in a potential leak of sensitive data.
CVE-2023-21255
A use-after-free was discovered in the in the Android binder driver, which
may result in local privilege escalation on systems where the binder driver
is loaded.
CVE-2023-21400
Ye Zhang and Nicolas Wu discovered a double-free in the io_uring subsystem,
which may result in denial of service or privilege escalation.
CVE-2023-31084
It was discovered that the DVB Core driver does not properly handle
locking of certain events, allowing a local user to cause a denial
of service.
CVE-2023-34319
Ross Lagerwall discovered a buffer overrun in Xen's netback driver
which may allow a Xen guest to cause denial of service to the
virtualisation host my sending malformed packets.
CVE-2023-35788
Hangyu Hua that an off-by-onein the Flower traffic classifier
may result in local of service or the execution of privilege
escalation.
CVE-2023-40283
A use-after-free was discovered in Bluetooth L2CAP socket handling.
For the oldstable distribution (bullseye), these problems have been fixed
in version 5.10.191-1.
