| CVE-2026-23195 | 1 Linux | 1 Linux Kernel | 2026-04-16 | 7 High |
| In the Linux kernel, the following vulnerability has been resolved: cgroup/dmem: avoid pool UAF An UAF issue was observed: BUG: KASAN: slab-use-after-free in page_counter_uncharge+0x65/0x150 Write of size 8 at addr ffff888106715440 by task insmod/527 CPU: 4 UID: 0 PID: 527 Comm: insmod 6.19.0-rc7-next-20260129+ #11 Tainted: [O]=OOT_MODULE Call Trace: <TASK> dump_stack_lvl+0x82/0xd0 kasan_report+0xca/0x100 kasan_check_range+0x39/0x1c0 page_counter_uncharge+0x65/0x150 dmem_cgroup_uncharge+0x1f/0x260 Allocated by task 527: Freed by task 0: The buggy address belongs to the object at ffff888106715400 which belongs to the cache kmalloc-512 of size 512 The buggy address is located 64 bytes inside of freed 512-byte region [ffff888106715400, ffff888106715600) The buggy address belongs to the physical page: Memory state around the buggy address: ffff888106715300: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc ffff888106715380: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc >ffff888106715400: fa fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb ^ ffff888106715480: fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb ffff888106715500: fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb The issue occurs because a pool can still be held by a caller after its associated memory region is unregistered. The current implementation frees the pool even if users still hold references to it (e.g., before uncharge operations complete). This patch adds a reference counter to each pool, ensuring that a pool is only freed when its reference count drops to zero. | ||||
| CVE-2004-0394 | 1 Linux | 1 Linux Kernel | 2026-04-16 | N/A |
| A "potential" buffer overflow exists in the panic() function in Linux 2.4.x, although it may not be exploitable due to the functionality of panic. | ||||
| CVE-2005-1765 | 1 Linux | 1 Linux Kernel | 2026-04-16 | N/A |
| syscall in the Linux kernel 2.6.8.1 and 2.6.10 for the AMD64 platform, when running in 32-bit compatibility mode, allows local users to cause a denial of service (kernel hang) via crafted arguments. | ||||
| CVE-2006-0039 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-04-16 | N/A |
| Race condition in the do_add_counters function in netfilter for Linux kernel 2.6.16 allows local users with CAP_NET_ADMIN capabilities to read kernel memory by triggering the race condition in a way that produces a size value that is inconsistent with allocated memory, which leads to a buffer over-read in IPT_ENTRY_ITERATE. | ||||
| CVE-1999-0074 | 4 Freebsd, Linux, Microsoft and 1 more | 4 Freebsd, Linux Kernel, Windows Nt and 1 more | 2026-04-16 | N/A |
| Listening TCP ports are sequentially allocated, allowing spoofing attacks. | ||||
| CVE-2006-1522 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-04-16 | N/A |
| The sys_add_key function in the keyring code in Linux kernel 2.6.16.1 and 2.6.17-rc1, and possibly earlier versions, allows local users to cause a denial of service (OOPS) via keyctl requests that add a key to a user key instead of a keyring key, which causes an invalid dereference in the __keyring_search_one function. | ||||
| CVE-2006-1862 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-04-16 | N/A |
| The virtual memory implementation in Linux kernel 2.6.x allows local users to cause a denial of service (panic) by running lsof a large number of times in a way that produces a heavy system load. | ||||
| CVE-2006-1857 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-04-16 | N/A |
| Buffer overflow in SCTP in Linux kernel before 2.6.16.17 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a malformed HB-ACK chunk. | ||||
| CVE-2001-1390 | 2 Linux, Redhat | 2 Linux Kernel, Linux | 2026-04-16 | N/A |
| Unknown vulnerability in binfmt_misc in the Linux kernel before 2.2.19, related to user pages. | ||||
| CVE-2004-0427 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-04-16 | N/A |
| The do_fork function in Linux 2.4.x before 2.4.26, and 2.6.x before 2.6.6, does not properly decrement the mm_count counter when an error occurs after the mm_struct for a child process has been activated, which triggers a memory leak that allows local users to cause a denial of service (memory exhaustion) via the clone (CLONE_VM) system call. | ||||
| CVE-2006-4538 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-04-16 | N/A |
| Linux kernel 2.6.17 and earlier, when running on IA64 or SPARC platforms, allows local users to cause a denial of service (crash) via a malformed ELF file that triggers memory maps that cross region boundaries. | ||||
| CVE-2004-0186 | 2 Linux, Samba | 2 Linux Kernel, Samba | 2026-04-16 | N/A |
| smbmnt in Samba 2.x and 3.x on Linux 2.6, when installed setuid, allows local users to gain root privileges by mounting a Samba share that contains a setuid root program, whose setuid attributes are not cleared when the share is mounted. | ||||
| CVE-2001-1398 | 2 Linux, Redhat | 2 Linux Kernel, Linux | 2026-04-16 | N/A |
| Masquerading code for Linux kernel before 2.2.19 does not fully check packet lengths in certain cases, which may lead to a vulnerability. | ||||
| CVE-2005-0136 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-04-16 | N/A |
| The Linux kernel before 2.6.11 on the Itanium IA64 platform has certain "ptrace corner cases" that allow local users to cause a denial of service (crash) via crafted syscalls, possibly related to MCA/INIT, a different vulnerability than CVE-2005-1761. | ||||
| CVE-2006-2444 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-04-16 | N/A |
| The snmp_trap_decode function in the SNMP NAT helper for Linux kernel before 2.6.16.18 allows remote attackers to cause a denial of service (crash) via unspecified remote attack vectors that cause failures in snmp_trap_decode that trigger (1) frees of random memory or (2) frees of previously-freed memory (double-free) by snmp_trap_decode as well as its calling function, as demonstrated via certain test cases of the PROTOS SNMP test suite. | ||||
| CVE-2005-0135 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-04-16 | N/A |
| The unw_unwind_to_user function in unwind.c on Itanium (ia64) architectures in Linux kernel 2.6 allows local users to cause a denial of service (system crash). | ||||

| Some futex functions in futex.c for Linux kernel 2.6.x perform get_user calls while holding the mmap_sem semaphore, which could allow local users to cause a deadlock condition in do_page_fault by triggering get_user faults while another thread is executing mmap or other functions. | ||||
| CVE-1999-0138 | 7 Apple, Digital, Freebsd and 4 more | 9 A Ux, Osf 1, Freebsd and 6 more | 2026-04-16 | N/A |

| CVE-2005-3105 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-04-16 | N/A |
| The mprotect code (mprotect.c) in Linux 2.6 on Itanium IA64 Montecito processors does not properly maintain cache coherency as required by the architecture, which allows local users to cause a denial of service and possibly corrupt data by modifying PTE protections. | ||||
| CVE-2006-0741 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-04-16 | N/A |
| Linux kernel before 2.6.15.5, when running on Intel processors, allows local users to cause a denial of service ("endless recursive fault") via unknown attack vectors related to a "bad elf entry address." | ||||
