A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc component can be exploited to achieve local privilege escalation.If a class with a link-sharing curve has a parent without a link-sharing curve, then init_vf will call vttree_insert on the parent, but vttree_remove will be skipped in update_vf. This leaves a dangling pointer that can cause a use-after-free.We recommend upgr ...

A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality. A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c.Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. Thi ...

A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality

Information exposure through microarchitectural state after transient execution in certain vector execution units for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

A Gather Data Sampling transient execution side-channel vulnerability was found affecting certain Intel processors. This issue may allow a local attacker using gather instruction to infer stale data from previously used vector registers on the same physical core. A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality. A buffer ...

A flaw in the Linux Kernel found in the GFS2 file system. On corrupted gfs2 file systems the evict code can try to reference the journal descriptor structure, jdesc, after it has been freed and set to NULL. It can lead to null pointer dereference when gfs2_trans_begin being called and then fail ingfs2_evict_inode. A buffer overrun vulnerability was found in the netback driver in Xen due to an unus ...

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 ...

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 kern ...

A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation.If tcf_change_indev fails, u32_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, l ...

A use-after-free flaw was found in the Netfilter subsystem of the Linux kernel when processing named and anonymous sets in batch requests, which can lead to performing arbitrary reads and writes in kernel memory. This flaw allows a local user with CAP_NET_ADMIN capability to crash or potentially escalate their privileges on the system. Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; ...
