  1. MediumCVSS 4.4 EPSS 0.16%

    In the Linux kernel, the following vulnerability has been resolved: dm-integrity: validate the superblock on resume dm_integrity_resume() re-reads the superblock from the device so that it picks up the flags and the recalculate position. It performs no validation on the result, w...

  2. MediumCVSS 5.5 EPSS 0.15%

    In the Linux kernel, the following vulnerability has been resolved: readdir: take no inode lock on an immutable directory iterate_dir() takes the directory's i_rwsem shared and holds it across ->iterate_shared(). For a directory that never has an entry and is never removed the lo...

  3. HighCVSS 8.8 EPSS 0.45%

    In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix heap out-of-bounds write in krb5_authenticate() In krb5_authenticate(), out_len is calculated to determine available headroom in response_buf for the incoming Kerberos AP-REP token. However, when SMB2_...

  4. HighCVSS 8.8 EPSS 0.16%

    In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Use active memslots for the per-vCPU MMIO cache KVM tags the per-vCPU MMIO cache with a memslot generation so that a memslot update invalidates cached MMIO information. Both the fill and validation path...

  5. HighCVSS 7.5 EPSS 0.52%

    In the Linux kernel, the following vulnerability has been resolved: bnxt_en: fix DMA mapping length for padded small packets Stefan Fleischmann reported Intel IOMMU DMA Read faults on BCM57412 NetXtreme-E NICs when transmitting packets on VLAN/macvlan interfaces: DMAR: [DMA Read...

  6. MediumCVSS 4.7 EPSS 0.20%

    In the Linux kernel, the following vulnerability has been resolved: fs: Free any excess xarray nodes in clear_inode() For many years we've had a hard to hit leak of xarray nodes. Hugh documented it well in commit 786b31121a2c. Recently people and syzbot have found ways to force i...

  7. CriticalCVSS 9.8 EPSS 0.46%

    In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Prevent stale XSK buffer release on refill retry When an XDP redirect to an AF_XDP socket fails because its RX ring is full, the XSK core frees the buffer. During the subsequent batched refill of a leg...

  8. CriticalCVSS 9.8 EPSS 0.46%

    In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Prevent stale XSK buffer release on MPWQE refill retry With AF_XDP on a striding RQ, mlx5e defers releasing XSK buffers until an MPWQE is refilled. If XSK allocation then returns -ENOMEM, actual_wq_hea...

  9. HighCVSS 7.4 EPSS 0.43%

    In the Linux kernel, the following vulnerability has been resolved: ipv4: udp: Create exceptions before socket matching Currently, when ICMP Fragmentation Needed and Redirect Message packets are locally delivered and quote a UDP packet, a FIB nexthop exception (FNHE) is only crea...

  10. HighCVSS 7.4 EPSS 0.17%

    In the Linux kernel, the following vulnerability has been resolved: ipv6: udp: Create exceptions before socket matching Currently, when ICMPv6 Packet Too Big and Redirect Message packets are locally delivered and quote a UDP packet, an exception is only created in the IPv6 except...

  11. LowCVSS 3.3 EPSS 0.19%

    In the Linux kernel, the following vulnerability has been resolved: rust_binder: reschedule node refcount update on thread exit When a thread exits via BINDER_THREAD_EXIT, its pending work items are cancelled. If a thread exits while holding a pending node refcount increment (e.g...

  12. MediumCVSS 5.5 EPSS 0.15%

    In the Linux kernel, the following vulnerability has been resolved: ipv4: stop PMTU walk when nexthop group shrinks Commit 7d3f3b4367f3 ("net: ipv4: Cache pmtu for all packet paths if multipath enabled") made __ip_rt_update_pmtu() update every path. For nexthop objects, fib_info_...

  13. MediumCVSS 5.5 EPSS 0.16%

    In the Linux kernel, the following vulnerability has been resolved: ipv4: stop exception dump when nexthop group shrinks Commit 4ce5dc9316de ("inet: switch inet_dump_fib() to RCU protection") allowed IPv4 FIB dumps to run concurrently with nexthop replacement. fib_dump_info_fnhe(...

  14. MediumCVSS 4.1 EPSS 0.16%

    In the Linux kernel, the following vulnerability has been resolved: ipv4: stop route notification sizing when nexthop group shrinks Commit 680aea08e78c ("net: ipv4: Emit notification when fib hardware flags are changed") added an RCU-only fib_nlmsg_size() call for asynchronous ha...

  15. LowCVSS 1.9 EPSS 0.21%

    In the Linux kernel, the following vulnerability has been resolved: ipv4: do not warn on route notification size race Commit 680aea08e78c ("net: ipv4: Emit notification when fib hardware flags are changed") added asynchronous route notifications for hardware flag changes. fib_ali...

  16. LowCVSS 1.9 EPSS 0.17%

    In the Linux kernel, the following vulnerability has been resolved: ipv6: do not warn on route notification size race fib6_info_hw_flags_set() sizes the skb with rt6_nlmsg_size() and later fills it with rt6_fill_node(). With nexthop compatibility mode enabled, a concurrent replac...

  17. LowCVSS 3.3 EPSS 0.17%

    In the Linux kernel, the following vulnerability has been resolved: ALSA: ctxfi: Fix memory leakage when clearing DAO input mappers Commit e576e7843c0d ("ALSA: ctxfi: Simplify dao_clear_{left,right}_input() functions") centralized the DAO input mapper clearing logic in dao_clear_...

  18. MediumCVSS 5.5 EPSS 0.16%

    In the Linux kernel, the following vulnerability has been resolved: can: dev: init_can_skb(): restore skb header initialization Commit 9f10374bb024 ("can: remove private CAN skb headroom infrastructure") removed the skb_reset_mac_header()/skb_reset_network_header()/ skb_reset_tra...

  19. MediumCVSS 4.1 EPSS 0.17%

    In the Linux kernel, the following vulnerability has been resolved: cgroup/cpuset: Handle cpu hotplug race in guarantee_active_cpus() With commit 2125c0034c5d ("cgroup/cpuset: Make cpuset hotplug processing synchronous"), the cpuset hotplug operation becomes synchronous. That com...
