FAQs regarding Amazon Linux ALAS/CVE Severity
An issue was discovered in the Linux kernel before 6.2. The ntfs3 subsystem does not properly check for correctness during disk reads, leading to an out-of-bounds read in ntfs_set_ea in fs/ntfs3/xattr.c. (CVE-2022-48502)
An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation.
The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-of-bounds write because lmax is updated according to packet sizes without bounds checks.
We recommend upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64. (CVE-2023-3611)
A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to achieve local privilege escalation.
If tcf_change_indev() fails, fw_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability.
We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f. (CVE-2023-3776)
An out-of-bounds read vulnerability was found in Netfilter Connection Tracking (conntrack) in the Linux kernel. This flaw allows a remote user to disclose sensitive information via the DCCP protocol. (CVE-2023-39197)
An issue was discovered in net/ceph/messenger_v2.c in the Linux kernel before 6.4.5. There is an integer signedness error, leading to a buffer overflow and remote code execution via HELLO or one of the AUTH frames. This occurs because of an untrusted length taken from a TCP packet in ceph_decode_32. (CVE-2023-44466)
In the Linux kernel before 6.4.5, drivers/gpu/drm/drm_atomic.c has a use-after-free during a race condition between a nonblocking atomic commit and a driver unload. (CVE-2023-51043)
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: Fix UAF in svc_tcp_listen_data_ready() (CVE-2023-52885)
A denial of service vulnerability due to a deadlock was found in sctp_auto_asconf_init in net/sctp/socket.c in the Linux kernel's SCTP subsystem. This flaw allows guests with local user privileges to trigger a deadlock and potentially crash the system. (CVE-2024-0639)
