Information exposure in the Linux kernel Hyper-V VMBus driver affects Confidential Computing (CoCo) guest VMs where a malicious hypervisor can force set_memory_encrypted()/set_memory_decrypted() to fail; the driver previously freed the still-shared (decrypted) pages back to the page allocator, potentially leaking confidential guest data to the untrusted host or causing memory corruption.

Use-after-free race condition in the Linux kernel IPv6 stack allows a network-adjacent unauthenticated attacker to corrupt kernel heap memory or crash the system by racing concurrent IPv6 address lookup and deletion operations. The `ipv6_get_ifaddr` function can return a pointer to an `inet6_ifaddr` entry whose reference count has already been decremented to zero by a concurrent `ipv6_del_addr` call, causing a subsequent refcount increment to operate on freed memory. No public exploit code exists and EPSS is at the 1st percentile, but the adjacent-network attack vector and high potential impact justify prioritized patching on IPv6-enabled systems.

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: reject new basechain after table flag update When dormant flag is toggled, hooks are disabled in the commit. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity.
Use-after-free race condition in the Linux kernel netfilter nf_tables subsystem allows a local attacker with low privileges to trigger kernel memory corruption during module teardown. The race exists between the asynchronous destroy workqueue (nf_tables_trans_destroy_work) and the exit_net cleanup path (__nft_release_table), confirmed by KASAN stack traces captured on kernel 6.8.0+: when the nf_tables module is removed while pending set element destruction transactions remain queued, the exit_net path frees the owning set before the workqueue processes the element. No public exploit code has been identified and EPSS sits at 0.01%, reflecting negligible current exploitation probability; this is not in CISA KEV.
Race condition in the Linux kernel's netfilter nf_tables flowtable subsystem exposes systems to potential kernel memory corruption via an unprotected concurrent list traversal. The `__nft_flowtable_type_get()` function iterates the `nf_tables_flowtables` list without RCU synchronization, allowing a collision with `nft_unregister_flowtable_type()` executing during module exit. Despite a CVSS score of 7.0 (High) with full C/I/A impact, no public exploit identified at time of analysis and an EPSS of 0.01% (1st percentile) indicate this is a maintenance priority rather than an active threat requiring emergency response.

Information exposure in the Linux kernel Hyper-V VMBus driver affects Confidential Computing (CoCo) guest VMs where a malicious hypervisor can force set_memory_encrypted()/set_memory_decrypted() to fail; the driver previously freed the still-shared (decrypted) pages back to the page allocator, potentially leaking confidential guest data to the untrusted host or causing memory corruption. The fix intentionally leaks (does not free) the affected pages when re-encryption fails, trading a small memory leak for guest confidentiality integrity. Fixed in stable kernel commits with no public exploit identified and no CISA KEV listing, though the assigned CVSS base score is 9.3 due to the confidential-computing trust boundary being crossed.

Use-after-free race condition in the Linux kernel IPv6 stack allows a network-adjacent unauthenticated attacker to corrupt kernel heap memory or crash the system by racing concurrent IPv6 address lookup and deletion operations. The `ipv6_get_ifaddr` function can return a pointer to an `inet6_ifaddr` entry whose reference count has already been decremented to zero by a concurrent `ipv6_del_addr` call, causing a subsequent refcount increment to operate on freed memory. No public exploit code exists and EPSS is at the 1st percentile, but the adjacent-network attack vector and high potential impact justify prioritized patching on IPv6-enabled systems.

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: reject new basechain after table flag update When dormant flag is toggled, hooks are disabled in the commit. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity.
Use-after-free race condition in the Linux kernel netfilter nf_tables subsystem allows a local attacker with low privileges to trigger kernel memory corruption during module teardown. The race exists between the asynchronous destroy workqueue (nf_tables_trans_destroy_work) and the exit_net cleanup path (__nft_release_table), confirmed by KASAN stack traces captured on kernel 6.8.0+: when the nf_tables module is removed while pending set element destruction transactions remain queued, the exit_net path frees the owning set before the workqueue processes the element. No public exploit code has been identified and EPSS sits at 0.01%, reflecting negligible current exploitation probability; this is not in CISA KEV.
Race condition in the Linux kernel's netfilter nf_tables flowtable subsystem exposes systems to potential kernel memory corruption via an unprotected concurrent list traversal. The `__nft_flowtable_type_get()` function iterates the `nf_tables_flowtables` list without RCU synchronization, allowing a collision with `nft_unregister_flowtable_type()` executing during module exit. Despite a CVSS score of 7.0 (High) with full C/I/A impact, no public exploit identified at time of analysis and an EPSS of 0.01% (1st percentile) indicate this is a maintenance priority rather than an active threat requiring emergency response.
