Summary
In the Linux kernel, the following vulnerability has been resolved: ice: fix memory leak in aRFS after reset Fix aRFS (accelerated Receive Flow Steering) structures memory leak by adding a checker to verify if aRFS memory is already allocated while configuring VSI. aRFS objects are allocated in two cases: - as part of VSI initialization (at probe), and - as part of reset handling However, VSI reconfiguration executed during reset involves memory allocation one more time, without prior releasing already allocated resources. This led to the memory leak with the following signature: [root@os-delivery ~]# cat /sys/kernel/debug/kmemleak unreferenced object 0xff3c1ca7252e6000 (size 8192): comm "kworker/0:0", pid 8, jiffies 4296833052 hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace (crc 0): [<ffffffff991ec485>] __kmalloc_cache_noprof+0x275/0x340 [<ffffffffc0a6e06a>] ice_init_arfs+0x3a/0xe0 [ice] [<ffffffffc09f1027>] ice_vsi_cfg_def+0x607/0x850 [ice] [<ffffffffc09f244b>] ice_vsi_setup+0x5b/0x130 [ice] [<ffffffffc09c2131>] ice_init+0x1c1/0x460 [ice] [<ffffffffc09c64af>] ice_probe+0x2af/0x520 [ice] [<ffffffff994fbcd3>] local_pci_probe+0x43/0xa0 [<ffffffff98f07103>] work_for_cpu_fn+0x13/0x20 [<ffffffff98f0b6d9>] process_one_work+0x179/0x390 [<ffffffff98f0c1e9>] worker_thread+0x239/0x340 [<ffffffff98f14abc>] kthread+0xcc/0x100 [<ffffffff98e45a6d>] ret_from_fork+0x2d/0x50 [<ffffffff98e083ba>] ret_from_fork_asm+0x1a/0x30 ...

the following vulnerability has been resolved:\\n\\nice: fix memory leak in aRFS after reset\\n\\nFix aRFS (accelerated Receive Flow Steering) structures memory leak by\\nadding a checker to verify if aRFS memory is already allocated while\\nconfiguring VSI. aRFS objects are allocated in two cases:\\n- as part of VSI initialization (at probe), and\\n- as part of reset handling\\n\\nHowever, VSI reconfiguration executed during reset involves memory\\nallocation one more time, without prior releasing already allocated\\nresources. This led to the memory leak with the following signature:\\n\\n[root@os-delivery ~]# cat /sys/kernel/debug/kmemleak\\nunreferenced object 0xff3c1ca7252e6000 (size 8192):\\n  comm \\\"kworker/0:0\\\", pid 8, jiffies 4296833052\\n  hex dump (first 32 bytes):\\n    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................\\n    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................\\n  backtrace (crc 0):\\n    [\u003cffffffff991ec485\u003e] __kmalloc_cache_noprof+0x275/0x340\\n    [\u003cffffffffc0a6e06a\u003e] ice_init_arfs+0x3a/0xe0 [ice]\\n    [\u003cffffffffc09f1027\u003e] ice_vsi_cfg_def+0x607/0x850 [ice]\\n    [\u003cffffffffc09f244b\u003e] ice_vsi_setup+0x5b/0x130 [ice]\\n    [\u003cffffffffc09c2131\u003e] ice_init+0x1c1/0x460 [ice]\\n    [\u003cffffffffc09c64af\u003e] ice_probe+0x2af/0x520 [ice]\\n    [\u003cffffffff994fbcd3\u003e] local_pci_probe+0x43/0xa0\\n    [\u003cffffffff98f07103\u003e] work_for_cpu_fn+0x13/0x20\\n    [\u003cffffffff98f0b6d9\u003e] process_one_work+0x179/0x390\\n    [\u003cffffffff98f0c1e9\u003e] worker_thread+0x239/0x340\\n    [\u003cffffffff98f14abc\u003e] kthread+0xcc/0x100\\n    [\u003cffffffff98e45a6d\u003e] ret_from_fork+0x2d/0x50\\n    [\u003cffffffff98e083ba\u003e] ret_from_fork_asm+0x1a/0x30\\n    ...\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.10.236\", \"versionStartIncluding\": \"5.8\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.15.180\", \"versionStartIncluding\": \"5.8\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.1.132\", \"versionStartIncluding\": \"5.8\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.84\", \"versionStartIncluding\": \"5.8\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.12.20\", \"versionStartIncluding\": \"5.8\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.13.8\", \"versionStartIncluding\": \"5.8\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.14\", \"versionStartIncluding\": \"5.8\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2025-05-04T07:26:32.029Z\"}}}",
