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. An issue in "Zen 2" CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information. 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. 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
