Summary
The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):
* kernel: inactive elements in nft_pipapo_walk (CVE-2023-6817)

High 7.8
Use-after-free in Linux kernel's netfilter: nf_tables component
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Due to a race condition between nf_tables netlink control plane transaction and nft_set element garbage collection, it …

High 7.8
In the Linux kernel before 6.4.12, amdgpu_cs_wait_all_fences in drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c has a fence use-…

High 7.8CVE-2023-5717 Public exploit
Out-of-bounds write in Linux kernel's Linux Kernel Performance Events (perf) component
A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf) component can be exploited to achieve local privilege escalation. If perf_read_group() is called while an event's sibling_list is smaller than its child's si…

High 7.8
Use-after-free in Linux kernel's netfilter: nf_tables component
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The function nft_pipapo_walk did not skip inactive elements during set walk which could lead double deactivations of PI…

High 7.8
Kernel: netfilter: use-after-free in nft_trans_gc_catchall_sync leads to privilege escalation
A use-after-free flaw was found in the netfilter subsystem of the Linux kernel. If the catchall element is garbage-collected when the pipapo set is removed, the element can be deactivated twice. This can cause a use-after-free issue on an NFT_CHAIN object or …

High 7.1
Kernel: out-of-bounds read vulnerability in smbcalcsize
An out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.
-
High 7.1
Kernel: oob access in smb2_dump_detail
An out-of-bounds read vulnerability was found in smb2_dump_detail in fs/smb/client/smb2ops.c in the Linux Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.
-
High 7.0
Kernel: ktls overwrites readonly memory pages when using function splice with a ktls socket as destination
An out-of-bounds memory write flaw was found in the Linux kernel’s Transport Layer Security functionality in how a user calls a function splice with a ktls socket as the destination. This flaw allows a local user to crash or potentially escalate their privile…

Kernel: null pointer dereference in nvmet_tcp_build_iovec
A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver and causing ke…
