{"id":"DEBIAN-CVE-2025-68297","details":"In the Linux kernel, the following vulnerability has been resolved:  ceph: fix crash in process_v2_sparse_read() for encrypted directories  The crash in process_v2_sparse_read() for fscrypt-encrypted directories has been reported. Issue takes place for Ceph msgr2 protocol in secure mode. It can be reproduced by the steps:  sudo mount -t ceph :/ /mnt/cephfs/ -o name=admin,fs=cephfs,ms_mode=secure  (1) mkdir /mnt/cephfs/fscrypt-test-3 (2) cp area_decrypted.tar /mnt/cephfs/fscrypt-test-3 (3) fscrypt encrypt --source=raw_key --key=./my.key /mnt/cephfs/fscrypt-test-3 (4) fscrypt lock /mnt/cephfs/fscrypt-test-3 (5) fscrypt unlock --key=my.key /mnt/cephfs/fscrypt-test-3 (6) cat /mnt/cephfs/fscrypt-test-3/area_decrypted.tar (7) Issue has been triggered  [  408.072247] ------------[ cut here ]------------ [  408.072251] WARNING: CPU: 1 PID: 392 at net/ceph/messenger_v2.c:865 ceph_con_v2_try_read+0x4b39/0x72f0 [  408.072267] Modules linked in: intel_rapl_msr intel_rapl_common intel_uncore_frequency_common intel_pmc_core pmt_telemetry pmt_discovery pmt_class intel_pmc_ssram_telemetry intel_vsec kvm_intel joydev kvm irqbypass polyval_clmulni ghash_clmulni_intel aesni_intel rapl input_leds psmouse serio_raw i2c_piix4 vga16fb bochs vgastate i2c_smbus floppy mac_hid qemu_fw_cfg pata_acpi sch_fq_codel rbd msr parport_pc ppdev lp parport efi_pstore [  408.072304] CPU: 1 UID: 0 PID: 392 Comm: kworker/1:3 Not tainted 6.17.0-rc7+ [  408.072307] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.17.0-5.fc42 04/01/2014 [  408.072310] Workqueue: ceph-msgr ceph_con_workfn [  408.072314] RIP: 0010:ceph_con_v2_try_read+0x4b39/0x72f0 [  408.072317] Code: c7 c1 20 f0 d4 ae 50 31 d2 48 c7 c6 60 27 d5 ae 48 c7 c7 f8 8e 6f b0 68 60 38 d5 ae e8 00 47 61 fe 48 83 c4 18 e9 ac fc ff ff \u003c0f\u003e 0b e9 06 fe ff ff 4c 8b 9d 98 fd ff ff 0f 84 64 e7 ff ff 89 85 [  408.072319] RSP: 0018:ffff88811c3e7a30 EFLAGS: 00010246 [  408.072322] RAX: ffffed1024874c6f RBX: ffffea00042c2b40 RCX: 0000000000000f38 [  408.072324] RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000000 [  408.072325] RBP: ffff88811c3e7ca8 R08: 0000000000000000 R09: 00000000000000c8 [  408.072326] R10: 00000000000000c8 R11: 0000000000000000 R12: 00000000000000c8 [  408.072327] R13: dffffc0000000000 R14: ffff8881243a6030 R15: 0000000000003000 [  408.072329] FS:  0000000000000000(0000) GS:ffff88823eadf000(0000) knlGS:0000000000000000 [  408.072331] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [  408.072332] CR2: 000000c0003c6000 CR3: 000000010c106005 CR4: 0000000000772ef0 [  408.072336] PKRU: 55555554 [  408.072337] Call Trace: [  408.072338]  \u003cTASK\u003e [  408.072340]  ?
