Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.
CVE-2021-44879
Wenqing Liu reported a NULL pointer dereference in the f2fs
implementation. An attacker able to mount a specially crafted image
can take advantage of this flaw for denial of service.
CVE-2023-5178
Alon Zahavi reported a use-after-free flaw in the NVMe-oF/TCP
subsystem in the queue initialization setup, which may result in
denial of service or privilege escalation.
CVE-2023-5197
Kevin Rich discovered a use-after-free flaw in the netfilter
subsystem which may result in denial of service or privilege
escalation for a user with the CAP_NET_ADMIN capability in any user
or network namespace.
CVE-2023-5717
Budimir Markovic reported a heap out-of-bounds write vulnerability
in the Linux kernel's Performance Events system caused by improper
handling of event groups, which may result in denial of service or
privilege escalation. The default settings in Debian prevent
exploitation unless more permissive settings have been applied in
the kernel.perf_event_paranoid sysctl.
CVE-2023-6121
Alon Zahavi reported an out-of-bounds read vulnerability in the
NVMe-oF/TCP which may result in an information leak.
CVE-2023-6531
Jann Horn discovered a use-after-free flaw due to a race condition
when the unix garbage collector's deletion of a SKB races
with unix_stream_read_generic() on the socket that the SKB is
queued on.
CVE-2023-6817
Xingyuan Mo 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-2023-6931
Budimir Markovic reported a heap out-of-bounds write vulnerability
in the Linux kernel's Performance Events system which may result in
denial of service or privilege escalation. The default settings in
Debian prevent exploitation unless more permissive settings have
been applied in the kernel.perf_event_paranoid sysctl.
CVE-2023-6932
A use-after-free vulnerability in the IPv4 IGMP implementation may
result in denial of service or privilege escalation.
CVE-2023-25775
Ivan D Barrera, Christopher Bednarz, Mustafa Ismail and Shiraz
Saleem discovered that improper access control in the Intel Ethernet
Controller RDMA driver may result in privilege escalation.
CVE-2023-34324
Marek Marczykowski-Gorecki reported a possible deadlock in the Xen
guests event channel code which may allow a malicious guest
administrator to cause a denial of service.
CVE-2023-35827
Zheng Wang reported a use-after-free flaw in the Renesas Ethernet
AVB support driver.
CVE-2023-45863
A race condition in library routines for handling generic kernel
objects may result in an out-of-bounds write in the
fill_kobj_path() function.
CVE-2023-46813
Tom Dohrmann reported that a race condition in the Secure Encrypted
Virtualization (SEV) implementation when accessing MMIO registers
may allow a local attacker in a SEV guest VM to cause a denial of
service or potentially execute arbitrary code.
CVE-2023-46862
It was discovered that a race condition in the io_uring
subsystem may result in a NULL pointer dereference, causing a
denial of service.
CVE-2023-51780
It was discovered that a race condition in the ATM (Asynchronous
Transfer Mode) subsystem may lead to a use-after-free.
CVE-2023-51781
It was discovered that a race condition in the Appletalk subsystem
may lead to a use-after-free.
CVE-2023-51782
It was discovered that a race condition in the Amateur Radio X.25
PLP (Rose) support may lead to a use-after-free. This module is not
auto-loaded on Debian systems, so this issue only affects systems
where it is explicitly loaded.
This update additionally fixes Debian bugs #1032104, #1035587, and #1052304; and includes many more bug fixes from stable updates 5.10.198-5.10.205 inclusive.
For Debian 8 jessie, these problems have been fixed in version 5.10.205-2~deb8u1.
For Debian 9 stretch, these problems have been fixed in version 5.10.205-2~deb9u1.
We recommend that you upgrade your linux-5.10 packages.
