| CVE-2026-43292 | 1 Linux | 1 Linux Kernel | 2026-05-08 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: mm/vmalloc: prevent RCU stalls in kasan_release_vmalloc_node When CONFIG_PAGE_OWNER is enabled, freeing KASAN shadow pages during vmalloc cleanup triggers expensive stack unwinding that acquires RCU read locks. Processing a large purge_list without rescheduling can cause the task to hold CPU for extended periods (10+ seconds), leading to RCU stalls and potential OOM conditions. The issue manifests in purge_vmap_node() -> kasan_release_vmalloc_node() where iterating through hundreds or thousands of vmap_area entries and freeing their associated shadow pages causes: rcu: INFO: rcu_preempt detected stalls on CPUs/tasks: rcu: Tasks blocked on level-0 rcu_node (CPUs 0-1): P6229/1:b..l ... task:kworker/0:17 state:R running task stack:28840 pid:6229 ... kasan_release_vmalloc_node+0x1ba/0xad0 mm/vmalloc.c:2299 purge_vmap_node+0x1ba/0xad0 mm/vmalloc.c:2299 Each call to kasan_release_vmalloc() can free many pages, and with page_owner tracking, each free triggers save_stack() which performs stack unwinding under RCU read lock. Without yielding, this creates an unbounded RCU critical section. Add periodic cond_resched() calls within the loop to allow: - RCU grace periods to complete - Other tasks to run - Scheduler to preempt when needed The fix uses need_resched() for immediate response under load, with a batch count of 32 as a guaranteed upper bound to prevent worst-case stalls even under light load. | ||||
| CVE-2025-69599 | 2026-05-08 | N/A | ||
| RayVentory Scan Engine through 12.6 Update 8 allows attackers to gain privileges if they control the value of the PATH environment variable. NOTE: this is disputed because ability of an attacker to control the environment is a site-specific misconfiguration. | ||||
| CVE-2026-21939 | 1 Oracle | 2 Database - Sqlcl, Database Server | 2026-04-18 | 7 High |
| Vulnerability in the SQLcl component of Oracle Database Server. Supported versions that are affected are 23.4.0-23.26.0. Difficult to exploit vulnerability allows unauthenticated attacker with logon to the infrastructure where SQLcl executes to compromise SQLcl. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of SQLcl.
